Should this read 2.6.35-rc3-git3?

If so, there's only about 20 commits in:
5904b3b81d2516..984bc9601f64fd

The likely fs related candidates are from Christoph and Nick Piggin
(added to CC)

No commits relating to POWER6 or PPC.

Not sure what's happening here. The first warning looks like some mutex
corruption, but it doesn't have a stack trace (these are 2 seperate
dumps, right? ie. the copy_process stack doesn't relate to the mutex
warning?) So I don't have much idea.

If it is reproducable, can you try getting a better stack trace, or
better yet, even bisecting if there is just a small window?

Thanks,
Nick

I can't reproduce the bug here on POWER6 or POWER7.

Pls let me know if this back trace would help in analyzing further.

The call stack for Badness at kernel/mutex-debug.c:64 (or whatever
