Sorry for taking so long to write back - I disabled APIC mode using the
noapic kernel boot parameter. And have been testing it for a few days
to fully confirmed that all the hardware is working properly - a touch
slower to boot, and can see a few things that were on separate
interrupts are now having to share. No major worries as everything is
working as it should be. I'm baffled as to why I can use APIC mode with
ndiswrapper and not get a flood of illegal register address messages and
the laptop is rock solid stable, but continuously get illegal register
messages & instability if I don't disable APIC mode while I use the ssb
with b43 driver. I wonder if the wireless adapter is doing something
abnormal/non-standard... :-(
