Otherwise it will panic with IO-APIC + timer not working. Differences in dmesg 2.6.22-rc6-mm1 has: [ 0.000000] Nvidia board detected. Ignoring ACPI timer override. [ 0.000000] If you got timer trouble try acpi_use_timer_override and [ 0.000000] ACPI: BIOS IRQ0 pin2 override ignored. and [ 0.000000] TSC calibrated against PM_TIMER 23-rc1-mm1 has: [ 0.000000] ACPI: IRQ0 used by override. [ 0.000000] ACPI: IRQ2 used by override. and [ 37.340319] ..MP-BIOS bug: 8254 timer not connected to IO-APIC I did not need to use acpi_use_timer_override with the older kernel. Do you need more info about my board/ BIOS/ ACPI tables? After the warm-boot trick 2.6.23-rc1-mm1 seems stable right now...
