Problem Description:
Stress testing of new quad-Opteron host triggers BUG at
fs/inode.c:1057. It more or less stable ( during a fiew hours )
occur under heavy load caused by dbench with concurrency 500
( dbench -c /usr/share/dbench/client_plain.txt 500 ) when dbench
reads/writes on XFS partition. I've tried to reproduce it on reiserfs
over the ~24 hours but with no success.
