Kernel panics on boot with Ubuntu 11.04 and 11.10 on HP Touchsmart TX2
 
Hi, ever since upgrading to Ubuntu (and Kubuntu) 11.04 (via clean install) on my HP Touchsmart TX2-1340ea, I've been getting the occasional (1 out of 3) kernel panics at boot.

This can happen off the live CD too, but just to be sure, I've replaced my hard drive, and checked my RAM with memtest86+

The BIOS's hdd tester says there's no problems with my drive either.

I have attached a screen shot of what my machine shows at panic:

I'm not using the ATI proprietary drivers (as they make graphics run even slower) and still causes kernel panics!

As I said, I can get panics on the installation CD, meaning the issue must lie in something on the default system.

Interestingly, I have to use BackTrack Linux for a course at Uni, which is based on 10.04 LTS, and my system is solid when running that.

Any Ideas? I have no idea how to even file a bug report, as there's no logged evidence of the crash!

Cheers

At the top of your screenshot there is a line containing:
udevd tainted P
That "tainted P" means that there is a proprietary module which may be causing the indigestion.

I imagine that you've probably run:
Code:

sudo apt-get purge fglrx
If not, and you don't want to use it, then you should.
Have you also checked for diversions? fglrx diverts (like an alias) some files. You can stop this as follows:
Code:

dpkg-divert --list
This will probably show some files "diverted". Use
Code:

sudo dpkg-divert --rename --remove
to get rid of these perversions.

One thing I forgot to mention is that the "tainted" process is usually different each time, I've had plymouth and modpobe do the same thing.

Doesn't explain the crashes on the Live CD though, but I'll try this

I'll give these commands a shot tonight anyway and report back, cheers.

After thinking about it, I remembered I am using a broadcom wifi card, and there could be a problem with the driver that's used in 11.04 onwards, as I somehow recall one of the two drivers being decommissioned (correct me if I'm wrong)!

I'll try removing my wifi card tonight and reboot a couple of times to see if I get a panic too.

Ok, here's what I've done, I've uninstalled the Catalyst drivers (well, installed and uninstalled them again)

Changed the wl driver for the b43 driver

Tried booting without the wireless card

Moved my hard drive to an identical machine (another HP Touchsmart TX2-1340ea)

And I'm STILL getting boot panics like this one:

The tainted process is different every time. I still have no idea how to bug report this!

Oops in interrupt - that's gotta be ugly.
You need to post the first oops (that last screen-shot isn't the first oops there) to lkml.org Be warned, that is a very active list, and they like things done (exactly) their way.
There is doco on how to capture and post oops' in the source tree - start with the top-level README. If you don't have a kernel source tree, try lxr.linux.no/linux

Have you figured out the solution to this problem? I have an HP Touchsmart 9300 and this happens to me as well with any kernel newer than 2.6.32 (newest Centos 6.2 kernel causes this too though - 2.6.32-71-229. 2.6.32-71.29 worked fine.).
