Hola,

I have an eMachines T6212 Opteron system on which the system clock
seems to run at ~twice the speed of the wall clock. The main board
is an ASUS K8 of some description with at ATI SB400 southbridge and
an ATI RS480 northbridge. Kernel version is 2.6.12.3.

If I disable ACPI, the clock slows down to what seems to be the proper
speed, but then my NIC doesn't work, presumably because it shares
an interrupt with something else.

I've tried booting with clock=tsc and clock=pit to no effect. Based
on my review of the list archives, there appears to be issues with
the chipset, but I haven't been able to sort out what the real problem
is and the appropriate solution.

There's an ACPI error that seems potentially troublesome:

ACPI: Subsystem revision 20050309
    ACPI-0352: *** Error: Looking up [\_SB_.PCI0.LPC0.LNK0] in namespace, AE_NOT_FOUND
search_node ffff81001fec9440 start_node ffff81001fec9440 return_node 0000000000000000

I also see this message from the PCI subsystem:

PCI: Ignoring BAR0-3 of IDE controller 0000:00:14.1

As a starting point, I've attached lspci output and the boot log. I'm
willing to provide more information and try patches and such.

Thanks.

Kurt
