About 2 minutes into "runalltests.sh" on ltp, ac kernels after 2.4.10-ac7
give a message like:
Oct 9 01:55:09 rushmore kernel: VFS: brelse: Trying to free free buffer
Oct 9 01:55:09 rushmore kernel: VFS: brelse: Trying to free free buffer
Repeatability: Good
Seen on:
2.4.10-ac8
2.4.10-ac10
2.4.10-ac10+eatcache
Not seen on:
2.4.10-ac4
2.4.10-ac7
2.4.11-pre2
2.4.11-pre6
Has occurred on every case with ac8 and ac10, and no test before.
Doesn't happen on Linus kernels.
Does not occur on my laptop, which is ext2 only.
Did not occur on Athlon when /tmp was mounted as ext2.
(LTP tests write a lot of files to /tmp).
I haven't tracked down which test generates the message yet, but it is
before the "personality" tests.

I might have missed something in the details, but you seem to be implying
this only happens on top of reiserfs. It does look like one of the
reiserfs patches in -ac triggers this, they are looking for the cause.

You are using reiserfs ? Certainly there appears to a buffer cache problem
with the remaining unmerged reiserfs changes from namesys that are in -ac.
