[Bug 667656] [NEW] soft-crash: task flush blocked for more than 120 seconds

Public bug reported:

since installing maverick on an amazon m1.large install i'm crashing
every 1-2 days. install is the alestic maverick EBS backed image: ami-
ca1f4f8f

also had the same happen once to a mounted volume (but not the root fs).
i have a very basic setup with purely userspace apps - nothing that
should be out of the ordinary.

thinking about reinstalling as 32bit and if that doesn't help
downgrading since i didn't have problems before maverick (was not on 64
bit before though).
