$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource
tod
(That's from 2.6.26.)

I already did something similar. Did you see my follow-up mail?
I added:
+ if (unlikely(clock->xtime_nsec < ((s64)xtime.tv_nsec << clock->shift)))
+ printk("Negative result: %llu - %lld\n",
+ (unsigned long long)clock->xtime_nsec,
+ (long long)((s64)xtime.tv_nsec << clock->shift));
Which resulted in:
Negative result: 166039808000 - 166039808256
Would you still like me to try your patch?
Cheers,
FJP
