Bugzilla 607650 is not accessible. I assume it is the same bug as the
one reported in:

https://bugzilla.redhat.com/show_bug.cgi?id=610911

I've been having instability problem with RHEL6beta 64-bit guest on a
Fedora12/13 host. So, I installed the test kernel referenced in the
above bug (host). This did not fix the problem for me. I am now
testing with the workaround in this announcement (guest).
