Subject: SCSI queue warnings under 2.6.31 with LSI SAS1064E controller
Date: Fri, 9 Oct 2009 03:07:16 +0000 (UTC) [thread overview]
Message-ID: <ham9d4$ihu$1@ger.gmane.org> (raw)
With apologies in advance if this is the wrong mailing list for this, after
upgrading from 2.6.30 to 2.6.31 I get the following warnings in syslog
frequently
Oct 9 12:19:21 jdc kernel: [ 1785.096275] sd 6:1:0:0: strange observation,
the queue depth is (64) meanwhile fw queue depth (65)
Oct 9 12:19:51 jdc kernel: [ 1815.312019] sd 6:1:0:0: Queue depth not changed yet
The Debian bug report is here
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=550190
Following a suggestion by Debian developers, I tried patching 2.6.31.3 with
this commit, but with no effect.
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=9d2e9d66a3f032667934144cd61c396ba49f090d
However, this also shows the problem can be reproduced under 2.6.31.3.
I would prefer to avoid running git bisect on this machine if I can, but I'll
gladly test a patch if it is unlikely to corrupt the file system.
HP XW6400 workstation, two SAS drives configured for striping, x86-64
architecture.
I haven't noticed any file corruption so far - I'm not sure how serious this
problem is.
