Yup.

I got the install to finish by doing this, but had to continue the installer
(with subsequent reboot) three or four times first. I also changed to the
network as the source for packages about halfway through (instead of
grabbing them from the CD). Some representative output:
panic: ffs_valloc: dup alloc

bootstrap failure
Retrying, type ^C to abort...
[etc]
At this point, I power cycled the machine and restarted the install.
I'm not using anything exotic for boot flags; just 'boot dqb1.1.1.16.0' at
the SRM(?) prompt.
I suppose I'm making so much hay about this because I want to make sure the
machine will be stable. It'll be co-located, although the facility is about
two blocks from where I work so the occasional lockup/power cycle isn't a
huge deal. Obviously, I'd like to avoid having that happen regularly. :-)
A couple questions about the CS20 itself if you don't mind, Stephen - have
you found a reasonable source of spare parts? I'm mostly interested in a
power supply or two to keep on a shelf, since they seem fairly nonstandard.
Also, I've heard references to remote management on these machines; in
particularly, a Lawrence Livermore Labs presentation mentioned using
PowerMan for remote power control. PowerMan has several methods of control,
so I'm not sure what the actual mechanism is.
thanks,
john
