Subject: frequent kernel BUG and lockups - 2.6.39 + xfs_fsr
Date: Sat, 6 Aug 2011 14:25:56 +0200 [thread overview]
Message-ID: <20110806122556.GB20341@schmorp.de> (raw)
I get frequent (for servers) lockups and crashes when using 2.6.39. 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.
