I determined it cannot happen in my source tree. When notsc is passed TSC CPUID is cleared and sched-clock works. I suspect what happens is that lguest forgets to clear the TSC cpuid bit when it disables TSC. Then the TSC frequency doesn't get computed and sched-clock can divide by zero.That's purely a lguest bug that needs to be fixed in lguest with a clear_bit(X86_FEATURE_TSC, &boot_cpu_data.x86_capability) somewhere -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
