Strangely enough, no.

Hmm, odd. It's a bit annoying when it happens, have to go hunt for a 
paper clip to stick in the hard-reset pin-hole. :( Presumably some 
kind of PROM interaction?

So not anytime soon then. I'll gladly test any proposed patches, if 
someone /were/ to try. (700MB IP32 box).

That is one reason why we can't debug it enough.

Indeed. If you see the problem again, could you try the following
commands to reset the watchdog register on ddb's "db>" prompt
(after sending break on your terminal):
db> w 0xb4000008 0x200
db> w 0xb4000030 0
db> reboot

(unfortunately my IP32 was dead recently...)

I have a vague notion this tends to happen most reliably after 
installing, and I usually netboot the installer. The reboot after 
install from disk hangs.

I wonder if perhaps the problem occurs only after you have bootp()'d 
a kernel?

Will try. Thanks!

I believe Jan Schaumann has/had an IP30 machine available for the 
IP30/IP27 port, and I at least would be pleased if these two projects 
were combined. It does pose additional work though. Also, depending on 
the location of the student I could offer my Indigo2.

Cheers,

Correct, I have an SGI Octane sitting around unused in Hoboken, NJ,
waiting to be picked up and NetBSDified.  Unfortunately, it's rather
heavy, so shipping is not really an option...

parts (but no hds), for your MIPS port? One caveat, unfortunately I do not have the means to cover shipping.

The Indigo2 and O2 should be suitable for the MIPS64 ISA project, and 
the Origin 200 for the port to IP30/IP27. I don't know yet where Qi Liu 
is located, and if more people are interested in porting to IP30/IP27. 
Re the shipping issue, I have no idea yet.

I'm in southern California, so I can't easily pick it up.  I don't know
the SoC student's location yet, but I have asked him.

Just to throw my Eur. 0.02 into the discussion: I have a dual-CPU Octane 
  sitting here unused for at least 2 years (due to ENOTIME) which I'm 
planning to sell in the near future. It's equipped with a PCI cardcage, 
too, so supporting PCI hardware is no problem either.
I'm located just outside Karlsruhe, Germany.
If anyone's interested in borrowing or buying the machine for a porting 
effort, let me know.

Cheers,
Gerald

Answer: Beijing, China.  I guess this makes a pickup in Hoboken NJ out
of the question. :-)

Thanks anyway.   In the meantime, if anyone else can help out, please

Re: sgi hardware donation

We have a 4D/25 (IP6) available in the UK.  Let me know if interested!
