Then again I knew when I got this machine what I might be getting myself into. Thanks for taking the time to help work on this and provide some ideas. I'll keep hacking on it and follow up here if I figure anything out. > At least you have it working in -ACPI -APIC mode. :-/ Unfortunately it seems that it's actually still broken in this case. I just discovered that even with the hint, the cardbus controller / devices don't generate any interrupts at all. The only reason it seemed to be working is that when I have the radio enabled, ath0 generates about 1000 interrupts/second (which seems high, but that's another discussion). So effectively is was just running in polling mode. I didn't notice that until this morning when I booted into single user mode and was trying to use some cardbus cards before ath0 was configured. Random tangent, it's kind of sad that one of the co-authors of the ACPI spec (Toshiba) would sell a machine that has so many problems with it. Though I think ATI deserves at least part of the blame as this appears to use one of their "system-on-a-chip" designs. Craig
