I have AMD too, vanilla kernel 2.6.27.6 and kvm-79 (although I have
this before 79).
the guest is SMP (UP guests hang too but less frequent).

depmod does not hang here (not reproducible). Heavy CPU + heavy IO on nfs mounts
triggers this on my side.

I have a very subjective feeling that it happens more frequently when
the host has
less uptime (freshly rebooted).
