Strange pygrub issue

[Orion Poplawski]

I've got a strange problem with one of my Fedora 11 guests on CentOS 5.4 
host.  pygrub does not report the current grub menu, but an old 
(previous) one.  So the system boots to an old kernel, despite 
everything seeming to be up to date in the guest.

Any ideas?

It's most likely: https://bugzilla.redhat.com/show_bug.cgi?id=466681

The workaround is to:

# echo 3 > /proc/sys/vm/drop_caches
