I saw the same problems using 3.0.0rc5, 5 and 6, and I think also 2.6.38. I don't see this lockups on 2.6.30 or 2.6.26 (all the respetcive latest debian kernels). The symtpom slightly differs - sometimes I get thousands of backtraces before the machine locks up, usually I get only one, and either the machine locks up completely, or only the processes using the filesystem in question (presumably) lock - all unkillable. The backtraces look all very similar: http://ue.tst.eu/85b9c9f66e36dda81be46892661c5bd0.txt this is from a desktop system - it tends to be harder to get these from servers. all the backtraces crash with a null pointer dereference in xfs_iget, or in xfs_trans_log_inode, and always for process xfs_fsr. I haven't seen a crash without xfs_fsr. -- The choice of a Deliantra, the free code+content MORPG -----==- _GNU_ http://www.deliantra.net ----==-- _ generation ---==---(_)__ __ ____ __ Marc Lehmann --==---/ / _ \/ // /\ \/ / schmorp@schmorp.de -=====/_/_//_/\_,_/ /_/\_\ _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
