Hi, thanks for the reply.

Unfortunately, the patch does not help. Attempt to start FreeBSD amd64
via quemu-kvm with -smp parameter greater than 1 fails in exactly the
same way as before.

The patch was applied to the kernel from the 3.6.11-1.fc17.src.rpm package.

Do I need some additional patches?
