OK, will try on 32-bit too.

Out of interest, what happens if you boot without SMP, either by
disabling HT in the bios or giving the hypervisor the "nosmp" boot
option? There may be a bad HT scheduling performance problem here; it
would be useful to eliminate that possibility.
My own boxes are either pure UP or genuine not-just-HT SMP, which may be
why I don't see this.
