This problem has actually been present quite a while (at least
since 2.6.0-test3). On my dual 1.25 GHz G4, it occurs once
every four boots or so.

Interesting. It happens with the NEC EHCI/OHCI or with the
KeyLargo OHCI's ? I suspect it's a problem of the NEC part,
and I think K2 actually contains that part built-in on the G5

The USB devices are all hooked up on the NEC EHCI/OHCI. I don't think the
KeyLargo OHCI cell is physically connected to any ports; it doesn't
show up in the device tree...

Ok, so something is wrong between those old Apple kbds and the NEC
part... Interesting. Does MacOS X show any similar symptom ? Also,
I suppose we could fix the OHCI driver to at least try to recover
in this case... I don't have much time to play with this at the
moment, but I'll keep that in mind. I need to find one  of those
bad kbds first ;)

Ben.
