Hi! Just for the records: On the Xeon 53xx, netbsd produces a few kernel messages before it dies with a protection fault:
kvm: msrs: 6 kvm: unhandled rdmsr: 0x1a0 inject_general_protection: rip 0xc0433a1c kvm: unhandled rdmsr: 0x1a0 inject_general_protection: rip 0xc0433a1c This is notably different from the behaviour on a Core Duo, maybe because the Xeon is running in 64-bit mode.
