I wouldn't trust the backtrace too much since it seems to keep
changing. It used to show __start_notes as the backtrace. This one is
with the head of Linus' tree as of a few minutes ago.
So I did a git bisect, and the problem goes back to June 11. The Warp
boots and seems to run fine. So I didn't notice until looking at the
logs for a different problem. I have since added a test to my
regression tests to look for badness or oops in the logs.
The git bisect returned:
871fa90791a6f83dd8e2e489feb9534a8c02088d is first bad commit
That is it, no more info.... strange. git show 8714...088d gives:
Merge: 7702667... 79f52b7...
Author: Linus Torvalds <torva...@linux-foundation.org>
Date: Thu Jun 11 11:27:09 2009 -0700
Merge branch 'for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/shaggy/jfs-2.6
* 'for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/shaggy/jfs-2.6: jfs:
Add missing mutex_unlock call to error path missing unlock in
jfs_quota_write()
The Warp has jfs disabled, so I don't know why it would affect us,
especially this realy in the boot! Anyway, I tried to revert the patch:
$ git revert 871fa90791a6f83dd8e2e489feb9534a8c02088d
fatal: Commit 871fa90791a6f83dd8e2e489feb9534a8c02088d is a merge but no -m
option was given.
So, anybody got an idea what is going on here? Or how I can revert the
patch. I am not a git expert, so if I am doing this wrong, let me know.
Cheers,
Sean
