Hello,
I finally got around to trying the -current kernel and it still
panics. Here is the trace (recall that the kernel doesn't panic when
the output-device is set to ttya so I had to type this in - there may
be some typos):

The machine is a powermac 9500 with a 2 x 200 mhz ppc604 daughtercard
and has NetBSD 2.0.2 installed.
Would it be worthwhile to file an official problem report?
Also, as a work around, is it possible to change the input-device and
output-device after the kernel is booted?
Thanks
Kjell
