Impossible to boot with latest kernel version

Oh... the last kernel working, that I can boot with, is 2.6.24-3, from -4 up to -7 none of them worked.

Hi Milo,

How comfortable would you be compiling and booting your own kernel? I've got a wiki page with instructions that may help a little: https://wiki.ubuntu.com/KernelTeam/GitKernelBuild

The reason I ask is that I was glancing through the kernel changelog descriptions, https://launchpad.net/ubuntu/+source/linux/ , and it looks like starting with the 2.6.24-4.6 kernel the CONFIG_B43LEGACY kernel config option was enabled whereas it was previously disabled. It would seem that this might be related to the issue you began seeing as of 2.6.24-4 . So I'm curious if you would be willing to build the Ubuntu kernel but disable this kernel config option and then retest. I can help you with building and booting your own kernel if the wiki isn't clear. The Ubuntu git kernel tree can be cloned from: git://kernel.ubuntu.com/ubuntu/ubuntu-hardy.git Hope that helps. Thanks.

Hi Leann,

I was planning on compiling vanilla 2.6.24 kernel, but I'll be cloning hardy's and work that out.

If I have any doubt/problem I'll contact you.

Compiling it without b43legacy and rebooting now works fine... the only problem is that my wireless card doesn't show up anywhere... (it didn't show up even with -3).

Hi Milo,

I'm glad to hear you can at least boot your machine now (after diasbling the config option). Regarding your wireless card not showing up, per the kernel team's bug policy, can you please attach the following information. Please be sure to attach each file as a separate attachment.

* uname -a > uname-a.log
* cat /proc/version_signature > version.log
* dmesg > dmesg.log
* sudo lspci -vvnn > lspci-vvnn.log

For more information regarding the kernel team bug policy, please refer to https://wiki.ubuntu.com/KernelTeamBugPolicies . Thanks again and we appreciate your help and feedback.

Also, it looks like the latest hardy git treee head has pulled in some recent changes for the b43legacy and b43 drivers:

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=shortlog

You may want to quickly retest. Thanks.

I will recompile it probably tonight or in the next couple of days.

By the way... I have a problem also with the battery of this laptop (last kernel with no problem was 2.6.20): it's not detected, it's like I'm always on AC. ACPI works, if I unplug, the brightness is dimmed, but no sign of the battery status.

Thanks Milo,

Care to open a new bug report regarding your battery issue. It's helpful to the development teams if the bug reports target one specific issue. Also just in clase it wasn't clear, the reason your wireless card isn't showing up anymore is because you've disabled the b43legacy driver which provides support for your wireless card. Please let us know your results after having tested the latest changes. Also, I'm curious what happens if rather than disabling the driver if you blacklisted it and then tried to modprobe it after you've booted. Does any more useful information show up in your dmesg output? Thanks!

Thanks Leann,

I've opened a new report.

Tonight I'm going to recompile the kernel and do the tests you said.

Bye!

Hi,

I've done all the tests:
- recompiled 2.6.24.2 (latest kernel cloned from git-ubuntu)
- booted normally: kernel freezes at b43legacy loading
- blacklisted b43legacy: boots fine
- modprobed b43legacy: freezes everything, even magickeys didn't work for recovery.

Cheers!

b43legacy is blacklisted.

I have done a completely new install with fresh hardy5 ISO, and the boot hangs at b43legacy loading... so it's not possible to boot.

Bye!

Same problem. Dell Inspiron 8200. I updated to the latest Hardy available today (4-22). If b43legacy is blacklisted I can boot, but modprob'ing b43legacy freezes the computer. I don't see how blacklisting the module can be considered "Fix released" though, since I cannot use my wireless without the b43legacy module? What are all of the Dell users supposed to do when suddenly Ubuntu freezes hard on their computer after a Hardy upgrade? What if they want to use WiFi?

Same problem with hp nx9010 hangs at the same place in the latest kernel...What to do now?

same problem here with compaq nx9110 broadcom 4303...
Shouldn't this bug remain open, as there is no fix, just a workaround yet, which does not actually provide the intended functionality?

Have a good day even without the wireless....

I had done a completely new install and still it's impossible to boot, it hangs on the b43legacy driver. Detaching the mini-PCI card I can safely boot.

Looking at /etc/modprobe.d/blacklist the b43legacy driver is not blacklisted.

Latest release of Ubuntu does not work out of box on my Fujitsu-Siemens D
Amilo 1840.

When I tried Ubuntu-beta a couple months ago it had the same symptoms as
described above. I hoped that Ubuntu team would fix it. But problem still
exists and I think it is very important to ignore it.

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.
