(Works with -no-kvm).
Using kvm 72 in 32 bit mode on the same hardware I get

Amusingly Xen 3.3 gives almost exactly the same bug, see http://bugzilla.xensource.com/bugzilla/show_bug.cgi?id=1391
Hi,
Would you be able to test this against a recent version of KVM? Trying to track
down old bugs, but have no way of testing unixware.
Cheers,
Jes
Bug still exists in recent Debian kernels.
