Yes, I tested it with a 2.6.25-something Fedora 9 pv-ops kernel (i386). I'll
send it along to Jens.

This is http://bugzilla.redhat.com/show_bug.cgi?id=459067, that I think you've
already looked at. Basically any F-10 or upstream git kernel is crashing on an
i386 RHEL-5 HV. We were a little confused by your comment in that bug, however;
we were under the impression that the fix you mentioned was specifically a
32-on-64 fix, not for 32-on-32. If we were wrong, please point it out.
Thanks,
