Comment # 15 on bug 1187264 from Ruediger Oertel

the STATEFILE.gz is a qemu migrate-to-file so it's a full dump of the state of
the VM including memory.

actually looking at a few of these stuck VMs the first BUG message printed
is not even a "Bad page state" but always seems to be "Bad rss-counter state"
