On my x86_64 machine, I got the following message
in log (kern = 2.6.23.14)
Jan 16 04:08:38 Astara kernel: BUG: MAX_LOCK_DEPTH too low!
Jan 16 04:08:38 Astara kernel: turning off the locking correctness
validator.
Have no idea what caused it as I found the message on my console
somewhat after the fact. The system had been up over 24 hours and
is still running. System still seems 'fine' (been up 3 days now),
so you can treat this as a "data point".

Are you perhaps an XFS user?

Funny you should mention that... yes. However, there were no
other messages that seem to indicate that the message had anything
to do with XFS. Nice shot in the dark.

:-), know issue, I guess I'll up the MAX_LOCK_DEPTH for the next
release. I looked at dynamically allocating that stuff, but that gets
awfully painful.
