So with those exact steps I managed to crash a real dual-core machine. So we can rule out any virtualization. This merely is related to whatever that command does and likely having more than one cpu. (It also worked / crashed on a local xen guest, so I can reproduce things locally). Next step will be to test latest upstream kernels to see whether this persists.
