Bug Description

Binary package hint: linux-image-2.6.24-16-generic

Just upgraded from 7.10 to 8.04. When trying to boot on the new 2.6.24-16-generic kernel am greeted with:

Kernel Panic: VFS: unable to mount root fs on unknown-block(0,0).

The older 2.6.22-14-generic kernel (post upgrade) boots just fine.

Don't know what information is needed to further troubleshoot this, please let me know.

GRUB menu.lst entries for the two kernels are identical apart from the vmlinuz files they reference, which are all present in /boot. I'd add that hard drives are connected through SATA.

different hardware, so should i file a separate bug?

my drive is IDE (it is actually a CF card with a CF to IDE adaptor).

i can still boot the 2.6.22-14-generic gutsy kernel

I compiled the vanilla 2.6.25 kernel from kernel.org (http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.25.tar.bz2) following instructions at https://help.ubuntu.com/community/forum/software/CustomKernel and system boots normally.

So somehow this is a problem with 2.6.24? There's discussion with SATA problems with 2.6.24 at http://lkml.org/lkml/2008/2/14/263 (and related thread) but those seem to be a little different than what I'm experiencing.

I'm getting the same problem, using an Intel ICH9 chipset. Drives are connected via SATA, but I'm using IDE mode rather than AHCI mode. Previous releases of Ubuntu had the same problem, this is some sort of regression?

Hi Guys,

Sorry for the delayed response. Daemacles, you mentioned you tested a 2.6.25 kernel and the issue was resolved. I'm curious if you'd be willing to test the upcoming Intrepid Ibex 8.10 Alpha release. It's based on the upstream 2.6.26 kernel. It would be good to at least know this does not exist in the upcoming release. http://www.ubuntu.com/testing . You should be able to test your bug using the LiveCD. Please let us know your results. We can then try to see if we can get a fix backported to Hardy. Thanks.

Leann,

Better late than never =)

I burned the Xubuntu 8.10 Alpha 3 LiveCD (http://cdimage.ubuntu.com/xubuntu/releases/intrepid/alpha-3/) and system boots up just fine.

Thanks for the feedback guys. Daemacles, the upcoming Intrepid release sounds promising. Now the tricky part is locating the appropriate patch(es) to backport to Hardy. This requires a bit of effort which we'd need your help with since you have the corresponding hardware to test with. You seemed comfortable building the upstream 2.6.25 kernel so I figured it doesn't hurt to ask. . . would you be willing to do a git bisect to try to narrow down the patch to backport. This is obviously completely at your own comfort level but will likely greatly increase the chance of getting this fix backported to hardy. The only other tricky bit is that when doing the bisect you'd need to flip the meanings of "good" and "bad" since you're trying to locate the patch which fixed the bug not caused the regression. The Ubuntu kernel git trees are listed here (you'll want to get the git tree for Intrepid):

https://wiki.ubuntu.com/KernelGitGuide

Information regarding building the Ubuntu kernel can be found here:

https://help.ubuntu.com/community/Kernel/Compile

Finally, information on doing a git bisect can be found here:

http://www.kernel.org/doc/local/git-quick.html#bisect

Again, doing this is completely at your own comfort level and is obviously not something we require you know how to do. We appreciate all the testing you've done so far. Please let us know your results if you do happen to venture performing the git bisect. Thanks in advance.

Leann,

  I'd love to give it a go...only way to learn more. I've never done anything with git before so give me a couple days to figure things out.

Hi All,

I have similar problem with my ASUS Maximus formula which has got Jmicron JMB368 PATA controller. If I disable this controller from BIOS, then Hardy boots fine but if it is turned on then Hardy does not boot.

I also tried the Alpha release of Intrepid Ibex 8.10 and I have no issues with this release. Should I also do the custom kernel compile to sort this issue in Hardy.

All,

I compiled the vanilla 2.6.26.2 kernel and now Hardy works fine. Is there a way I can get the 8.10 kernel backported to Hardy?

Hi Guys,

Just marking this "Fix Released" against Intrepid and opening a Hardy nomination. Thanks.
