Hmm, ok, I have no idea about the root cause of this problem, but I did
notice one thing about selinux_cred_free() that's different than most
other freeing functions in the kernel. It does not accept a NULL value.
Most other freeing functions will just return if passed NULL, but
selinux_cred_free() will crash.
I wonder if it would make sense to add a NULL 'short circuit' to that
function? If so, please pick up the patch below.

This particular error is almost certainly fixed by rc3's patch below.
Whether your earlier errors are a side-effect of the same Uptodate bug
I cannot say: it's conceivable, but I don't see it as likely. Maybe
you should just move up to rc3 and see what happens with that.

Subject: ext4: fix setting random pages PageUptodate
X-Git-Tag: v2.6.37-rc3~1^2~5
X-Git-Url: http://127.0.0.1:1234/?p=.git;a=commitdiff_plain;h=08da1193d2c8c7a25d0cef7f85d0b9f1ad7c583a
ext4: fix setting random pages PageUptodate
ext4_end_bio calls put_page and kmem_cache_free before calling
SetPageUpdate(). This can result in setting the PageUptodate bit on
random pages and causes the following BUG:
BUG: Bad page state in process rm pfn:52e54
page:ffffea0001222260 count:0 mapcount:0 mapping: (null) index:0x0
arch kernel: page flags: 0x4000000000000008(uptodate)
Fix the problem by moving put_io_page() after the SetPageUpdate() call.
Thanks to Hugh Dickins for analyzing this problem.

the kernel barfed this up, on waking up from suspend.. I've tried to
reproduce this but haven't.(will see if I can, then will do a bisect)
also I've had to revert commit: 6a4f3b52377 due to another issue
so maybe that is a factor in this..
