this is likely a problem with virtualbox.

Comment 3 Dave Jones 2011-06-07 17:50:55 UTC

hmm, that said, there are also some similar traces in bugzilla from vmware, and also from qemu.  This might be indicative of a bug with virtual block devices.

bug 708718 is the untainted qemu bug (this is the one that we'll focus on, given the lack of tainted modules if you want to follow along).

bug 709946 is an example of one of the vmware traces.
