I have a problem with clock drift on an opteron machine running suse 9.2. I think I've narrowed the problem down to the kernel clock. I stopped NTP so that isn't confusing the issue. I manually set the system clock and the hardware clock to match another NTP-synchronized clock that is working properly and left it for an hour. The hardware clock is still showing the correct time, but the system clock has gained 52 minutes in an hour. Can anybody suggest where to start looking for the source of the problem? Thanks, Dave

I din't find an answer here, but the problem is now resolved so here's the solution for posterity: Go into the BIOS and enable ACPI 2.0 so that the kernel can find the HPET. The motherboard is a Tyan Thunder K8S Pro but it may also apply to other mobos. Credits: I asked my supplier (DNUK), he asked Tyan, they asked SuSE! Thanks, all. Dave
