Ok, that's what I eventually figured by looking at the code as well.

Wait a minute, this is a new board. I had a suspicion, and I have a new suspect, can we investigate this?
I have used the same kernel, with the VIA 686a patch, but left some config options out:
# diff -U1 -Nur <(egrep -v '^(#|$)' linux-2.2.18-ma3/.config) <(egrep -v '^(#|$)' linux-2.2.18-try/.config) --- /dev/fd/63 Thu Dec 28 11:20:05 2000 +++ /dev/fd/62 Thu Dec 28 11:20:05 2000 @@ -30,6 +30,2 @@ CONFIG_PARPORT_PC=m -CONFIG_APM=y -CONFIG_APM_CPU_IDLE=y -CONFIG_APM_DISPLAY_BLANK=y -CONFIG_APM_RTC_IS_GMT=y CONFIG_BLK_DEV_FD=y I rebooted, and since I left APM out, the system clock is alright since 63 mins. Might the APM BIOS CPU IDLE calls be related? I did *not* enable CONFIG_APM_ALLOW_INTS. I'll investigate this right now and report back what I find.

Where is the source for the adjtimex /program/? SuSE don't bring adjtimex.
