System Clock Twice as Fast FX-55

I installed gentoo on my new AMD64 FX-55. Went pretty smoothly. One glitch is the system time is unning exactly 2x real time. The BIOS time is correct on reboot.

Googled and saw some answers for BSD with a similar issue. Solution was:
/etc/sysctl.conf and add kern.timecounter.hardware=TSC

I didn't see anything similar in
/proc/sys/kernel

Any help from the hardcore gentoo'ers would be much appreciated.

Thanks.

I'm probably not 'hardcore', but maybe I can help

In a recent thread or two that I've seen regarding time drift and consitently incorrect times, some people reported that renaming or deleting /etc/adjtime fixed the issue (it'll be recreated). Other things to check are the CLOCK variable in /etc/rc.conf and your /etc/localtime symlink.

Thanks.

Well, I tried all those suggestions, and the clock is still spinning while the hw clock maintains the real time.

I also tried --adjust, --hctosys, but the clock doesn't want to slow down... I typed these as fast as I could, and it's still drifting.

odd, ive never come across clock drift.

do you have rtc compiled in the kernel also you could check out ntp for a network time. are you sure its not your bios or something funny like that.

I updated the kernel sources, and recompiled. System clock is correct now. Thanks for our help!
