Thanks for providing the info. According to the IDs your and my board are=20
quite alike. If you don't pass acpi_use_timer_override to vanilla kernel,=20
does your timer get connected to IO-APIC? Ie:

           CPU0
  0:      47834   IO-APIC-edge      timer

In this mode, is your board stable? I never run my hw longer than 10h, so I=
=20
cannot say anything about long-term stability, but lately my nforce2 didn't=
=20
make any troubles and (when it did, it usally was related to PSU). I am=20
skipping the override, ie. my timer is connected to IO-APIC.

If in the latter mode your hw is instable, we have a problem...
