As pointed out by Vitaly, this is probably the guest RFLAGS corruption bug[*],
especially since it's XP specific (more likely to trigger emulation). The fix
should make its way to Linus' tree this week, and hopefully to stable kernels
shortly thereafter. Though if you can manually apply and test the fix before
then, that would be very helpful.
