Subject: PM / hibernate xfs lock up / xfs_reclaim_inodes_ag
Date: Tue, 12 Jul 2011 18:05:01 +0200	[thread overview]
Message-ID: <4E1C70AD.1010101@u-club.de> (raw)

Hi!

I'd like you to have a look into this issue:

pm-hibernate locks up when using xfs while "Preallocating image memory".

https://bugzilla.kernel.org/show_bug.cgi?id=33622

I got at least this backtrace (2.6.39.3)
