(Changed the subject to correspond with email.)
I am having the same problem on the 64-bit host running RHEL5.1 as well, it
just takes more reboots. Same symptoms as I mentioned for the 32-bit host.
kernel side stack traces for each qemu thread for one of the lockups is
attached; the file contains traces for each thread at 3 sample times in case it
helps get some insight.
