Ext3 users - Dec 2002 - [Fwd: 2.5.53: VFS: brelse: Trying to free free buffer]

hm, this backtrace actually has info...

btw, I think we need this:

But it's not the cause.

Kernel is 2.5.53 (pulled from bk, so it might have a changeset or two
applied after 2.5.53) compiled with all debug options enabled. The
filesystem is on an IDE drive, ext3 with htree enabled. I'm not very
sure how the error came up, I think it was during copying something from
a CD-ROM. Do let me know if there is any other info I should provide.
