Finally had success with my old Toshiba T4800CT laptop
and NetBSD 1.6.  The only problem was with the PCMCIA
system on the default kernel.  As soon as I did an
ifconfig on the 3c589 PCMCIA card, the system would crash:

uvm_fault(0xc02ee5e0 ...)
kernel: page fault trap, code =3D 0
Stopped in pid 6 (ioflush) at pmap_change_attrs + 0xac...

The trace started at pmap_change_attrs() and eventually
came from sched_sync().

Was able to rebuild a new kernel and changed the PCMCIA
options from the default in the usual way:

options PCIC_ISA_ALLOC_IOBASE=3D0x300
options PCIC_ISA_ALLOC_IOSIZE=3D0x0ff

and the 3c589 works great!

Should having these set to the default cause the system
to crash?

For info the dmesg on this machine is follows:
