Hi
I have a Sunfire V100 (UltraSparc II) on which I have just installed
OpenBSD 5.8.
I have persistent "stray" interrupts on Psycho. The machine is unable to
run for
more than a few minutes.
The latest event is
"panic uncorrectable DMA error AFAR ce846258 (pa=0 tte=0/cc992012) AFSR

All this was written down in a difficult physical environment, and is my
best effort, but may not be perfect.
I do have the results from ps as pictures taken with my phone if you
really, really need them.
this machine was running OpenBSD 5.5 OK till a few days ago. I presume it
will be impossible to fix this on the machine, as it does not run for long
enough, and will reinstall
5.5 unless you advise me that I can do something that will fix it within 24
hours.

Andrew
