That's probably either the pci quirk that got added to do USB host

the device without doing pci_enable_device or checking whether MMIO is
enabled. A fix has gone into Linus' tree for that.
There was also a bug added to the adbhid.c driver which would cause an
oops when you pressed a key if you had an ADB keyboard (which
powerbooks do). That's also fixed in Linus' tree.
It was neither of those -- after a few warnings about sleeping in
inappropriate contexts it just seems to stop. The Pegasos is a little
more informative -- lots of 'hda: lost interrupt' on that. Keyboard
seems to work though, and Bogomips calculation -- so maybe it's just PCI
interrupts which are missing. I'll poke at it further.
I'll also try again on the powerbook today and see if I can get anything
more useful out of it.
