I installed CentOS 4.4 32 bit on a dual core AMD64 motherboad. Its a
Tyan Tomcat K8E motherboard with socket 939. The clock keeps drifting
off like 5+ minutes an hour. Run ntpupdate hourly to compensate.
Any ideas why or how to fix?
Probably a buggy/unsupported apci setup. Look for a bios update, or
use the kernel options 'clock=pmtmr' or 'clock=pit'
Yup, I've had similar problems with some Tyan Opteron systems (even with
current bios). In /boot/grub/grub.conf add a kernel parameter like so:
title CentOS (2.6.9-42.0.8.EL)
root (hd0,0)
kernel /vmlinuz-2.6.9-42.0.8.EL ro root=LABEL=/ clock=pmtmr
initrd /initrd-2.6.9-42.0.8.EL.img
Cheers,
