Hi Konrad, Does this look at all familiar? There is some more info in the full bug log at http://bugs.debian.org/637234 . In particular, contrary to the message below, the user subsequently confirmed that the issue appears to be Xen specific (doesn't happen on native or vmware) and that it arose between 2.6.39-2-686-pae and 3.0.0-1-686-pae. Could it be related to edf6ef59ec7e "xen-blkfront: Introduce BLKIF_OP_FLUSH_DISKCACHE support"? That looks like the only pertinent change between 2.6.39 and 3.0. Gedalya, 2.6.39-2-686-pae could be anything from v2.6.39..v2.6.39.2 please could you confirm which package version you have installed in case it makes a difference. Cheers, Ian.
