This is the "one device goes south but everything else is happy" sort
of problem I was complaining about last week.
My UP1000 running today's -current just wedged while I was rcp'ing a
large file to it over a 100Mb link. It's busy speweing "fxp0: device
timeout" Everything but the nic seems happy. (But since I'm running
with NIS and NFS, loosing the nic is fatal)
The machine's state is as follows:
Stopped at siointr1+0x17c: br zero,siointr1+0x32c <zero=0x0>

Is there a chance that this is being caused by the kernel, say,
getting a clock interrupt in the middle of doing some low-level
should-be-atomic timing-dependant I/O operations in either the driver
or the I/O support routines?
Remember that on the UP1000, everything goes through the isa interrupt
controller.
