Regression: bug: int 14 cr2... booting 2.6.28 in jaunty fails on ASUS P5q and maybe others

bug 310075 could be related because i810drm modules are now built in to kernel.

Boot without initrd is succesful. Livecd gives also error when booting.

I have nearly the same issue here. I just did a fresh install from the current livecd (which booted fine), but when booting from the hard disk, I get the same "BUG: INT 14: CR2 ff..." type message. The message appears nearly instantly after the kernel has started, so something very early in initialization is triggering it.

If I delete the initrd line from the grub entry and specify the root partition by hand, then the kernel is able to boot all the way to a fully working userspace.

I've never tried any other Jaunty kernels other than 2.6.28-4 on this system, so I don't know if it's a regression from 28-3 for me or not.

Same here for 2.6.28-5 - 2.6.27-11 boots successfully.

Board is a Asus P5Q-pro.

If you need further informations/assistance - let me know :)

oh, 2.6.28-6 came out just recently - same bug as the 2(?) kernels before.

This could be a regression off these:

http://lkml.org/lkml/2008/10/9/267
http://bugs.archlinux.org/task/12255

So i did a little bit of research and it cleared out that my last post is right.

Its a regression of the patch described here:
http://lkml.org/lkml/2008/10/9/267

This patch was reverted here:
https://lists.ubuntu.com/archives/intrepid-changes/2008-October/009184.html

Beside the revert messages, I couldnt find any reason for the revert.

Anyhow, I took the latest kernel source 2.6.28-6 (which, btw, dont boot either) and patched it with the patch from above. After the build and install the system boots as expected.

I think we need the kernel-team to get in touch with this but I dont know how. any help to get this fix back would be really appreciated.

Before kernel 2.6.27.2 came out I submitted that patch to Ubuntu.
As soon as Ubuntu updated to 2.6.27.2 the patch has been dropped because it has been applied upstream since that version.

Then in 2.6.28-1.1 the upstream patch has been reverted: https://lists.ubuntu.com/archives/jaunty-changes/2008-November/001218.html
The changelog says:
  [ Upstream Kernel Changes ]
  * Revert "x86, early_ioremap: fix fencepost error"

Which is just wrong as this patch has never been reverted upstream.
So please drop that reverse patch as it surely causes the same problems as is Intrepid.

I installed 9.04 Beta on a mini-itx system with a VIA processor and experienced this bug with the latest kernel...

FYI - system info:
http://mini-itx.com/2007/12/10/via-launch-artigo-pico-itx-builder-kit

2.6.28-11-generic <------ crashes

2.6.27-11-generic <----- WORKS

The specifics are:

BUG: Int 14: CR2 ffffb0f0

etc...

I'm getting this too on a Via EPIA-5000 system (Via Samuel 2 cpu) on 2.6.28-11-generic.

I'll just go and mark the bug I placed a duplicate of this one; sorry. :-)

I have the same error on Asus P4T533-C with Ubuntu 9.04 final

"BUG: Int 14" is a generic error message, so you probably hit another bug.

If you have some time you can debug the problem by using git bisect (http://kerneltrap.org/node/11753) and open a new bug report.

I'm having the same type of issue as above. As i have a different motherboard I've entered it in as a new bug here: https://bugs.launchpad.net/ubuntu/+bug/366587

I'm hoping Ben or Felix might be able to confirm if mine is the same issue or just another issue that looks almost the same.
Cheers and thank you in advance.

linux-image-2.6.28-11-generic 2.6.28-11.41 (RC) and 2.6.28-11.42 (final) on amd64 work fine for me (ASUS P5QL-Pro).

Thank you. that confirms that it is a different bug. Cheers.

I just got the same bug on a Desktop, intel based chipset. not a common bug (Yesterday we had an install fest in my country, and we didnt see this happening (More than 200 installs). I'm actually using Jaunty Final release...

Same bug here, unable to boot with latest kernel up to date

Mainboard: Intel DQ965COKRMX1 GbE RAID

i have the same problem , ubuntu 8.10 has work`d but the new 9 version give me that error on boot (from hdd , cd , usb)

so i found in bios an option that after i have disable it ubuntu work`s fine .

Memory Hole At 15M-16M you must disable this option .

(more about function of tis option here http://www.techarp.com/showfreebog.aspx?lang=0&bogno=109 )

also you may see attached picture to this post.

Thanks a lot.

Anyway I left kubuntu and I installed ubuntu and everything worked fine.

I saw that option, unfortunately I cannot test it now because I've
reinstalled and I've no more the broken kubuntu.

Thanks again for your kindness.
Ciao.
Marco.

I see the same error in the same circumstances with Ubuntu 9.04 Server i386 (Kernel 2.6.28-11-generic) on a Mac Mini 1.66 GHz Core Duo.

Also hit by this bug with kernel 2.6.28-15, booting fine with old 2.6.24-24 (have not tried with intermediate versions). If the initrd is not used, the kernel boots fine as indicated in previous posts. At first sight, there is no problem in using the system after booting without the initrd (how necessary is the initrd? any disadvantage for not using the initrd at boot?).
As the size of the kernel has increased a lot from 24-24 to 28-15 (almost double size), I think that the system cannot cope with the larger kernel and the initrd at the same time. What are the memory requirements for booting with 2.6.28-15 plus initrd?
Updating BIOS changes nothing for me, my BIOS has not either the "Memory Hole" option anywhere.
