On x86, there is no OOps, it just freezes. On ia64, I get a nice MCA
and from that we can infer that a USB host controller read from
address 0xf0000000 caused the problem but since this is asynchronous
to the kernel's code path, the instruction pointer etc. in the MCA
state dump isn't terribly helpful. Actually, just now I got a case
where the ia64 machine hung (it does this occasionally, instead of
MCAing). In this case, I got similar "timeout" messages as on the x86
box and the backtrace looked like this:
Call Trace:

The machine still responded to ping's but was otherwise unreachable.

No, if I only load the OHCI HCD, the kernel doesn't crash.
Greg> If not, can you get us the output of /proc/bus/usb/devices and

Sure, they're attached. Note: there are devices other than the BTC
keyboard connected, but I verified that the same problem occurs even
when the BTC keyboard is the only USB device plugged into the machine.
Greg> If not, does then loading the hid driver cause the problem?
Yes, it's the loading of the hid driver that's triggering the crash.
