netconsole support on Cobalt systems... Anyone tried it?

Hi All,

I've been tinkering with my Qube2 tonight, seeing if I can get
netconsole running.  I'd like to get this running for two reasons:

(1) I've only got one null-modem cable, which usually is plugged into my
Indigo2 Impact -- I'd like to leave it where it is if possible.
(2) I'd like to improve support for the Qube 2700, which lacks such
interfaces.

I've looked around on the web, but haven't found a great deal of
material that explains how one uses it.  The best resource thus far has
been the linux/documentation/network/netconsole.txt file, as well as a
crash dump[1] from an AMD64, which shows netconsole in action.

I tried booting with `netconsole=9877@10.0.0.1/eth0,9876@10.0.0.254/` on
the kernel command line, without success.  The system continues to
boot[2], but only outputting to the serial console.

Has anyone here, tried using netconsole on Cobalt hardware?  Has anybody
played with netconsole on _any_ hardware?

Regards,

2. I was using my WinCE/MIPS-based[3] PDA, which happens to have a
crippled version of "HyperTerminal".  Unfortunately, it lacks any
ability to capture the text... but otherwise, turns my PDA into a very
convenient portable VT100. :-)

3. I'd like to get Linux working on this thing sometime... see my next
post, which I'll write in a moment. :-)
