Bug Description

I keep getting lots of kernel panic, using ubuntu natty stock kernels and kernels from kernel-ppa :
2.6.38-8, 2.6.38-10, 2.6.39-0 and even 3.0 kernel.

It's odd that it spans so widely. Each time I took a picture of the laptop screen, and it seems to be related very closely to ecryptfs (which I use for a 550GB /home partition).

The bug is reproductible 100% of the time : I just need to order the system to shutdown or reboot : I get a kernel panic everytime.

Screen pictures are attached.

I forgot to mention I'm using a Toshiba Portégé R830 Laptop, 8 GB RAM, 750GB hd.
This bug happens on the same computer, but different harddisk (I had to change it after another kernel panic mi-july..).

I don't know if this is related, but I got two other kind of kernel panic :
- one with 2.6.38-8 with a usb modem-manager problem it seems (usb_submit_urb), and
- one with 2.6.39-0 still with usb modem-manager (__wake_up_common).

Should I post those pictures too ?

Thanks for taking the time to upload the photos, Alexandre.

I can't reproduce this bug, but I've seen another report of this happening: https://bugzilla.kernel.org/show_bug.cgi?id=37292

I've uploaded a proposed patch to that bug, which can be found at: https://bugzilla.kernel.org/attachment.cgi?id=66942

If someone that can consistently reproduce this bug would give that patch a shot, I'm pretty confident that it is the fix for this bug.

I could do that, but it's been perhaps 8 years since I compiled my own kernel, so I need a refresher !

First, against which source should I use the patch ? 3.0 ? 2.6.38 ?
Then, how to apply it ? Then I guess `make oldconfig` is the way to go ? Or perhaps one of those magical cmdline which create nice debs ?

John,

I just subscribed you to this bug. Here's a kernel panic reported by a user, and a patch that Tyler would like tested, but he's unable to reproduce the issue.

The reporter here can reproduce the bug reliably, but cannot easily build a kernel.

Could you please upload a test kernel into a PPA or somewhere to make Tyler's proposed fix testable?

Thanks!

memtest_freeze.jpg Edit (74.3 KiB, image/jpeg)

On a sidenote, I don't know if it's related, but I tried to memtest my 8GB of RAM to check if the other random crashes I experience could be caused by those.

For some unknown reasons, whenever I choose "Memtest86" or "Memtest86 serial console" in the grub2 menu, it opens the Memtest screen, then it freezes (except the little red "+" sign next to "Memtest" in the upper part of the screen which continues to blink, and my fan goes up like crazy...leaving me no choice but to hard reset the laptop.

I'll try when I'll have more time to use memtest from a liveusb.

Screenshot of the faulty memtest attached.

Kernel panic 2.6.39-0, reiserfs ? Edit (125.5 KiB, image/jpeg)

It's totally insane the number of kernel panic I'm getting on that computer !!

This time it happened when trying to unmount an external hd. I doubt it's related to the previous KP, but why not post it here...

:'(

12 years I use Linux, never so that many kernel panic in the last 2 months.
Funny point : I bought the exact same computer for my wife and installed the same kubuntu distribution on it, and it rolls without any problem (though, I use a lot more different applications, but same kernel and no ecryptsfs..).

Please note that proposed fix that I mentioned in comment #32 didn't fix the issue.
