I was stumped by something similar for a while too. I was trying to find out why it would begin to boot (as yours
does) , then freeze, and reboot. After poking around in the sgimips code, I noticed that dbaud is set to 384800
(there is code to read dbaud here, but it's commented out AFAIR). My dbaud was set to 9600.
As soon as I changed dbaud in the O2 prom, it came up and has been happy ever since. (I've built kernels and
such on the thing since.)
I don't know if this is your problem of not, just thought I'd throw this out there for the archives.
