Clock 3 times faster vs. APIC - Known Bug?

Hi there,

have a strange behaviour for a couple of weeks with my PC after I updated: when I boot my PC the clock is going to fast.
That means for example booting my computer at 10:00 am after one minute it shows 10:03 am.

That results in a lot of strange behaviour (keyboard to fast, can not emerge --sync, etc.)

The only workaround I found out is to pass the kernel parameter "noapic acpi=off" - after that (and deleting
/etc/adjtime) everthing works normal (instead of the acpi which I switched off - also annoying)

Trying again and deleting "noapic acpi=off" in the kernel parameter, rebooting the PC, once again the clock is working 3 times
faster.

Somebody knows what I can do to switch on acpi AND having a normal clock?

Thanks for any advice

Holm

Hi,
I had same behavior on <2.6.22 kernel. Upgrade to >=2.6.22 + upgrade BIOS
solves the problem (I have Asus M2N4 SLI Motherboard). If you will have any
problems/kernel panic (with timers) when booting try add "apic=debug"
to your boot manager kernel command line (it works for me).
