Subject: BUG: MAX_STACK_TRACE_ENTRIES too low!

Hi there,

just before upgrading from -rc9 to -final, this showed up in the logs:

BUG: MAX_STACK_TRACE_ENTRIES too low!
turning off the locking correctness validator.

  =======================

A quick search on the net tells me, this has been reported around ~2.6.18, 
but this was back in 2006. My box here is still running fine, and I'm not 
sure how to reproduce this one - there hasn't been much I/O when the BUG 
occured. I just wanted t have this reported...

Full dmesg and .config: http://nerdbynature.de/bits/2.6.25-rc9/

Thanks,
Christian.
