Our ncr(4) driver is not so great in general and is not fully
bus_dma'ified, so it has coherency problems.

I could try reconfiguring it to use I/O cycles instead of memory as
a workaround..

BTW, if you also have dmesg and /proc/pci for this system, that would
be nice to have.

Ok, assuming that's a Linux init binary you are running there, things
seems to be okay this far (we don't have Linux emulation on MIPS yet).

Try using the /arc snapshot binaries for a root system (netboot is
probably the most convenient).

Remember to replace a few files from etc/etc.cobalt and regenerate
/dev. If you don't have a separate NetBSD system with an anoncvs tree:

I too have a RaQ 2 (single ethernet and no SCSI), so you will likely
the same as me. Note the once you start stressing the system, you
will hit a weird interrupt priority bug that I have been unable to
find so far.

You ended in the kernel debugger, DDB.
