Hi all, this is my first post here, but I'm running into a frustrating issue with my Octane. I've decided to wipe my system and do a fresh IRIX install (the hard disc came with whatever IRIX the previous owner had). Following the instructions for a netinstall mostly from here:
https://wiki.irixnet.org/network_install_ubuntu
using an Ubuntu VM as my network install host, I'm able to consistently get to the miniroot install, then it asks me to create a new file system. When I do, and choose the 4096 block size per guidance here:

(my drive is 70GB), I get the following error screen:

Code:

WARNING: odsy_earlyinit re-entered. Init code probably paniced!
PANIC: CPU 0: TLBMISS: KERNEL FAULT
PC: 0xa80000002018cbe0 ep: 0xa800000020ba3ba8
EXC code: 8, 'Read TLB Miss '
Bad addr: 0xc0000fc000000000, cause: 0x8<CE=0
NOTICE - cpu 1 didn't dump TLB, may be hung
Reboot started from CPU 0
CPU 0 rebooting

Then nothing--just hangs there.

I've tried reseating all the boards, reseating the ram, and I'm still getting this crash (third attempt now). System info:

Octane, older mobo revision, 2x195MHz R10k, 768MB ram, MXE+SE dual head. 

I'm using the 6.5.22 netinstall files from the irixnet FTP.

Any thoughts on next steps I could take to figure out what's up here? I guess I could remove my dual head and go down to a basic graphics setup. I'm not sure why it's saying "odsy_earlyinit" I hope it doesn't think I have Odyssey graphics for some reason. The only other clue I have is the fact that CPU 1 "didn't dump TLB, may be hung"--could I have a bum CPU? Never had any issues running the system before the wipe.

Any help appreciated.
