Indeed.  If it had and Intel processor or chipset
I might be better equiped to help debug it...;-)

of course you're on your own when using ndiswrapper...

ERR interrupts are not a good sign.

Really a box with multiple CPUs should not be run in noapic mode...

Thanks for the acpidump output.

The code below makes OSI(Linux) clearly a NOP on this box,
since the value it writes would get over-written by any
of the Windows OSI strings -- and Linux sets all the Windows OSI strings....

I'll add this box to the NOP DMI list.
