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. Mar 4 21:20:12 burly kernel: BUG: soft lockup - CPU#0 stuck for 11s!
