Well guys, the mystery deepens. I got a new backplane on ebay, tried the install again, same issue. Got a new motherboard/CPU/ram combo on ebay (it was a reasonable deal, and an upgrade from 2x195->2x250), same issue. Went headless: removed video card, set console to serial, booted to serial console, same issue.

One big clue I get on the serial console though, because the screen clear doesn't actually screen clear, is the text above the "PANIC" line:

A), CPU 0 disabled. But I don't think that's the issue, and I can just turn it back on in the prom easily enough. B) This seems to happen immediately after it tries to set up swap space. I've already tried doing a sequential write exercise of the disc (multiple times, which basically kills a day each time). Since I effectively have a completely new system at this point, the only variable remaining is the HDD. At this point, I almost want to see if someone would just pre-install IRIX on a whole new drive for me for a fee...If you know anyone who does that, I'm deep into the pay-to-just-get-it-working space. Otherwise, I'll have to order a new SCSI disc and see if that solves my problem. No idea how far down the money pit goes.

What a pain. Kinda like owning a classic Jag. Or a boat.
