This is could be due to the fact that VMware workstation doesn't
implement a flush cache command which is fine, but we didn't set the
drive to ready after the error.  If you can compile your kernel here is
a patch which will fix the problem of the cacheflush timing out but I'm
not sure if it will help at all with the hard hang.
