[ACPI] workaround for nForce2 BIOS bug: XT-PIC timer in IOAPIC mode "acpi_skip_timer_override" boot parameter
this should help the stablility but you have to place "acpi_skip_timer_override" as boot parameter

[PATCH] fixup for C1 Halt Disconnect problem on nForce2 chipsets
Based on information provided by "Allen Martin" <AMartin@nvidia.com>:
A hang is caused when the CPU generates a very fast CONNECT/HALT cycle
sequence. Workaround is to set the SYSTEM_IDLE_TIMEOUT to 80 ns.
This allows the state-machine and timer to return to a proper state within
80 ns of the CONNECT and probe appearing together. Since the CPU will not
issue another HALT within 80 ns of the initial HALT, the failure condition

Is this a driver issue? I was assuming that is the case since my exact same config setup has worked with 2.6.0-2.6.5... but I'm certainly not saying that's what it is for sure. Let me know if more info is needed, or what config options I should change.
