Hi
Some days ago I started noticing strange time jumps on my Athlon system. (Asus board, VIA chipset, AMD Athlon 650MHz processor). I haven't noticed them before and I am pretty sure there weren't any for the last few years! Uptime of the machine is now 218 days, and problems began appearing after 215 days approximately.
What happens: when doing a $ while true; do date; done I'm noticing time jumps _exactly_ at the beginning of a "new" second (or at the end of an "old" one). the jump is exactly 4294 (4295) seconds into the future. Example: ... Mon Aug 4 18:11:06 CEST 2003 Mon Aug 4 18:11:06 CEST 2003 Mon Aug 4 19:22:41 CEST 2003 Mon Aug 4 19:22:41 CEST 2003 Mon Aug 4 19:22:41 CEST 2003 Mon Aug 4 18:11:07 CEST 2003 Mon Aug 4 18:11:07 CEST 2003 ...
I've found some previous discussions about this about a year ago:
http://www.ussg.iu.edu/hypermail/linux/kernel/0203.3/0557.html http://www.ussg.iu.edu/hypermail/linux/kernel/0206.0/1505.html
What seems strange to me is, that these jumps have never occured before. The machine is running a plain 2.4.20 kernel.
So my question is: will disabling the CONFIG_X86_TSC option and passing "notsc" as boot parameter fix the problem? Or did I get something wrong there?
thanks patrick
