Now that this subject is rolling... I have a very similar (probably the
same) problem on an R4400 Indigo2. The panic says:

	trap: TLB miss (load or instr. fetch) in kernel mode
	status=0x40003, cause=0x10000000, epc=0x0, vaddr=0x0
	pid=82 cmd=dev_mkdb usp=0x0 ksp=0xca567e88
	Stopped in pid 82 (dev_mkdb) at          0:   invalid address.
	db>

hinv says:

	System: IP22
	Processor: 250 MHz R4400, with FPU
	P. I-cache: 16 kB
	P. D-cache: 16 kB
	S. cache: 2048 kB
	Memory: 128 MB
	Graphics: MG10 Impact
	Audio: Iris Audio Processor: version A2 rev. 1.1.0

This machine boots from the net, install done by extracting the tar
archives on the host platform and making devices, configuring /etc,
etcetera...
Booting only works from a terminal, due to the GIO graphics card
(details can be found in a previous thread).

The machine is not capable of compiling kernels, due to cc and cpp
segfaulting frequently, presumably because of aforementioned problem.
I have succesfully installed a number of packages.

I'm trying to collect more complete information, but there are a number
of things in the way. One of them is that I apparently don't have a
dump device to dump the kernel cores to. What do I need for that?

Attached is the dmesg output, with another kernel panic in between the
mentioned one and a successful login for the dmesg output.
