Hi, after almost 50 days of uptime I suddenly noticed an extreme clock drift in current. Here is an excerpt from my /var/log/messages (March 8th was my last reboot time):

After a reboot everything was OK again. The drift began exactly at the moment the counter for clock interrupts got past the 2^31 mark (I have HZ=500 in the kernel): 500 ticks/s * 49.7 days ~ 2^31 ticks After a reboot everything went ok again.
