I did indeed have a zero tsc_khz, and my system does mark TSC unstable (falling back to acpi-pm). But I've never once booted the host kernel on this laptop with "notsc". I've experimented with booting a guest with notsc to see if it would help. As a further datapoint, rc6-mm1 host and guest works. > Anyway, if the host decides not to use the TSC, the guest shouldn't use > it, which is the basis of this patch...
