I'm using amd64 2.6.15-r5 gentoo and I've noticed that my clock is really fast. (date shows Mon Feb 27 01:50:37 EST 2006 when it's 19:50 on the 26th, and I corrected the clock yesterday afternoon.)

my /etc/conf.d/clock:

Are you running an AMD Athlon 64 X2 (Dualcore)?

I put this in lilo.conf and it fixed my crazy clock

I don't have those issues, using amd64 3400+ on 754 socket.

Why don't you try using ntp?

I'm running an AMD 64 3400+ and my clock ran at an insane speed, I found my solution in the amd64 forum under the sticky FAQ. I used this kernel parameter in my grub menu and it seemed to solve the problem, "noapictimer" but without the quotation marks obviously. If that doesn't work for you try one of the other kernel parameters said to work in the amd64 FAQ.

In lilo.conf (append="") or after the kernel in grub.conf (kernel="") try passing no_timer_check as a boot argument.

If that doesn't work try passing disable_timer_pin_1

If that doesn't work try passing noapictimer

If that doesn't work try passing irqfixup

If that doesn't work try passing irqpoll

Which one works if any depends mostly on whether you are running it in 64-bit mode or as a 32-bit processor. The first one is for 64bit.

Also if possible use ntp on boot.
