Running kvm 62 on 2.6.24.3 (the extraversion is reported due to a local
patch to vfat) I just got a couple of soft lockups and a hang. I was
installing FreeBSD 7 at the time.
I am trying again with v2.6.25-rc3-369-g976dde0.
Here are the wossnames.

Can you reproduce and send the output of sysrq-t? Looks like the timer
callback is stuck.

I'll give it a lash.
I was able to complete the installation with kvm 62 on 2.6.25-rc3-369-g976dde0.
