Comment 7 for bug 222174

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... :-(

The info I snipped about the Broadcom board:
