[STAGING] (Regression) Kernel panic with 2.6.38-8 and acpi on

Made some testing with mainline kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ on my desktop PC (Acer Aspire M7811 )

With all natty releases tested (2.6.38-2, 2.6.37-6, 2.6.36-4) I've got the kernel panic problem with acpi=on.
Unfortunately no bootstrap so no logs.

With 2.6.33-02063307-generic (a maverick release) acpi work and the machine is up and running.

Can I do other tests or produce more documents to help find the bug?

The same behavior on my Acer Extensa 2902LMi with Ubuntu 11.04.

I can confirm this to be the case for my Sony Vaio VGN-CR520E

I have the same problem with My Acer Aspire 4820TG
For all kernels < 2.6.38.3 I can boot, but for any newer kernel it's just a blank screen.

This is only the case when I have switchable graphics enabled in BIOS (it boots perfect on just the discrete card) and am running the non-proprietary driver for my ATI5650 card. It boots using fglrx , but then vgaswitcheroo doesn't work.

When setting ACPI=OFF my wireless is locked in off position as well.

I have the same problem. Also when I boot with acpi=off my touchpad and wifi do not work.

https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/+bug/774005
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/774671

In my case either acpi=off with the standard kernel or just the pae-kernel (without acpi=off) did help.

Many bugs have been refried as a duplicate of this bug,

Helping people on this support forum sticky:
http://ubuntuforums.org/showthread.php?p=10740083#post10740083
We;ve found that most of the time where they would need to use acpi=off or noacpi to get graphics to work, that it did cause other acpi related problems.

We further found that if they manually set the GRUB_GFXMODE=[WIDTHxHEIGTH|xDEPTH] in /etc/default/grub and further added a vesa vga mode set to the kernel boot line via vga=xxx, where xxx is a supported vesa mode by their hardware, that they no longer needed the acpi=off kernel mode set switch... and "everything" started working correctly again.

These all seemed to be related to this bug: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/781445
Which ties into this upstream bug: https://savannah.gnu.org/bugs/?33318

What seems to be happening with all these interrelated problems is that If we manually set the parameters that grub should query and pass on... Then things work.

If not and set to the defaults of "auto" which spawns some processes to find and pass data to the kernel, then something is broke in those early processes and is passing invalid data.

Unfortunatley, this all means that the problem is upstream in that last referred bug.

Woohoo ... latest kernel (2.6.38.10) solved this problem for me!

No - I still have to use the PAE kernel (in that case 2.6.38.10).

GREAT! Latest kernel (2.6.38.10) solved this problem for me, too!

proposed kernel 2.6.38-10 is booting without problems (with acpi on) on my Extensa 2902LMi. This kernel update seems to fix it for me :)

Installed 2.6.38.10 from update-proposed.
No change for me: still not booting and kernel panic with acpi=on

I think this is a mainline kernel bug, in any case.

Same problem here on an old Thinkpad W500.

I am chiming in as well. I have a Lenovo B510 All-in-one, i5 processors, 6GB RAM, 1 TB hard drive, ATI Radeon 5570, and tried to dual boot 11.04 64 bit. It wouldn't boot from CD/DVD, but booted through BIOS, and I didn't get any further than the language/Try/Install when I got the lagging black screen. I tried the acpi=on on and a few other options and still the same issue.
I ended up installing 10.04...now my Wacom won't work (ha!), but I am hoping an upgrade won't give me the same results as a fresh install.

Consequently, it installed with no problems on my old computer (inVidia graphics card, with a bad hard drive), but the fan stayed on and abruptly shut down...again, bad hard drive, overheating problem, and not the Ubuntu install.

Bug affects me also - HP i5 laptop with Intel graphics. I can boot with acpi=off, but this causes extremely high cpu temperatures. All other attempts at recovery have failed. Performed online upgrade from Ubuntu 10.10, which was running fine.

Same thing here for me. I upgraded from 10.10 which worked fine. Upon reboot, I got the ubuntu image, then it had edbuntu splash screen (which is inexplicable to me because I never installed Edbuntu but rather Netbook Remix and was upgrading from that. I have a Compaq 110c which has the Intel 945 graphics chipset. It's a dual boot system with XP.

Maurizio Daniele, thank you for reporting this and helping make Ubuntu better. This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please capture the oops following https://wiki.ubuntu.com/KernelTeam/KernelTeamBugPolicies#Capturing_OOPs ? As well, can you try with the latest development release of Ubuntu? ISO CD images are available from http://cdimage.ubuntu.com/releases/ .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux <replace-with-bug-number>

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Hello, thanks to you to work to made Ubuntu better.

Actually this bug is still an issue. I get a kernel panic anytime I activate acpi.
At this moment I use Ubuntu 11.10 with kernel-image 3.0.0-16-generic #29-Ubuntu SMP

I made some testing with mainline kernel (latest: linux-image-3.2.0-030200rc4-generic_3.2.0-030200rc4.201112012035_amd64) without any change. I think the problem is somehow connected to my mainboard (H57M01 by Acer) but updating to the latest firmware didn't solve.

I didn't get any log from lkcd, but maybe I made something wrong with this tool (first time I use it)

Next I will test the pangoline beta-1 with new kernel and post my results here.

addendum:

Please note that in the previous log acpi is diabled. If you need an apport information with acpi enabled, please tell me, I try to post one before the system crash (actually it's boot and then crash after a couple of minutes)

Hello.

I finally manage to test the Pangoline live DVD (beta2).
Same result with 3.2.0-17 AMD64 kernel. The box boots and then crashes after a couple of minutes.

I could copy the panic screen before reboot, please see attachment. I hope this can be useful.

I 'will soon test the 3.3 kernel too.

Updated to 13.04 (kernel 3.8.0-19). Nothing changed, bug is still present.

Status changed to 'Confirmed' because the bug affects multiple users.

Note: Previous comment was wrong.
Affects: linux-image-3.8.0-19-generic (X86_64)

Maurizio Daniele, thank you for testing Raring.

Could you please provide a discussion on why you pass the kernel parameter:
acpi=on

As well, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the mainline kernels archive directory daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.9

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags:
kernel-unable-to-test-upstream
kernel-unable-to-test-upstream-VERSION-NUMBER

Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding.

Subject: NEEDS MORE HATS.

I think a lot of hate comes from people just not picking it up and continuing to hold on to that feeling. For instance, there's the whole section of playstation gamers who don't get to play and so probably default to disliking the game. Then there's the 'problem' with the game which I believe there is only one that is truly fatal for Titanfall's mass popularity and that is Respawn 'taking out', or not including some of the rubbish bullshit that you see in modern fps games, such as lots of weapons, flashy xp meters and customisation. For me, I'm glad these are not in the game but it's sad that the reason that rubbish *is* in cod and battlefield is because it keeps people playing and that's really all that tf really needs.

Subject: I have a joke for you...

Is the litterbox tucked into the corner of a room, or closely located next to the other litterbox?

Snow is uncomfortable with her new surroundings and probably doesn't feel safe taking a poop when Ellie could sneak up on her at any moment. Separate their litter boxes and put Snow's in a place where she can see in all four directions. Doesn't have to be the middle of the room, but have enough space that Snow can run in any direction if she feels threatened.

Also, if you and your girlfriend used different substrate in the litter boxes, but now have Snow using a new one, try changing her back to what she had before.

Your girlfriend agreed to move in with you and make compromises along the way, but her cat never did. Snow's probably a bit pissed off at the whole situation.

I watched this clip on mute at first. The part where Sasha stomps Charlotte in the gut was a "whoa!" moment from me. It was a brutal move of aggression from a vicious and intimidating opponent.

Then I watched it again with the commentary and learned that it was an example of Sasha's "tenacity."

Cause that's what double-stomping someone's guts is. Tenacity.
