I have a new dual Opteron 248 system here with an MSI K8T Master2-FAR
mainboard that isn't happy with 2.6.0-test. In fact, it's not altogether
happy with any SMP kernel so far, but will boot RedHat's 2.4.21EL single
processor kernel and appears to function normally.

I'm having problems compiling 2.6.0-test9 through bk22 on this box,
erroring here:

I've tried various -mm patches, but error elsewhere:

I removed ACPI support and the kernel built and booted, seeing both
processors, but the tg3 driver wouldn't load, not finding the hardware,;
the 2.4.21EL kernel has no issues with this module. Is there a patch I'm
missing? 

There was significant oddness with this kernel, however, as top would
show CPU stats oscillating between 33.3% irq, softirq, and iowait per
CPU, and 0.0% every odd second. This was on a quiescent system.

I can compile 2.6.0-test9-bk22 from Arjan's source RPM successfully. I'm
obviously missing a patch. Regardless, an attempt to boot any 2.6.0
kernel, single or SMP fails on load with a 

slab: error in check_poison_obj(): "biovec-#" object was modified after
freeing

then a slew of acpi-related errors rapidly scroll ad infinitum.

A SMP boot of RedHat's 2.4.21-4.1EL kernel gives back:

Code: bad RIP value

then a call trace to stop_this_cpu.

A straight install of SuSE SLES 64 simply won't boot, as the kernel
2.4.19 kernel is SMP, and panics with the same error as above.

I don't have an older Opteron box, so I can't tell if this is related to
the new CPUs or not.
