Subject: [2.6.33.3] scheduling while atomic (inode reclaim races still?)
Date: Thu, 20 May 2010 01:31:04 -0700	[thread overview]
Message-ID: <20100520083104.GA4723@hostway.ca> (raw)

This started happening on host about 10 days after upgrading to 2.6.33.3
(in hopes that it fixed all of the reclaim issues present in 2.6.33.2). 
I don't see any fixes in 2.6.33.4 relevant to this particular issue.

After this first error, the kernel logs just filled with repeat
occurrences with different backtraces.
