Hi,
I'm insane and I do that for a long time, because I don't really have a
lot of options there.

I'm on Centos 5 without problems here, both with 5.1-release and -current
snapshot. The performance is horrible as always, though.

Hint: when you are seeing crashes inside a context switch, someone may
be interested in what processes took part in the switch, like "show proc
$rdi" and "show proc $rsi". Then, "sh reg" and "x /x,30 $rsp" for
starters. (pity it won't fit all on one screen)
Also, you can say if you ran other versions of OpenBSD on the same
configuration, or messed with the hypervisor's kernel lately, or if it
is a new install on an out of the box dom0 that just happens to fail.
