Nope.  And from what I can tell from the person who was on-site, the box =
was not responding to anything but a hard reset.  And I accidentally =
wedged the onboard IP-KVM by ssh=92ing to that and poking around with no =
knowledge of what the non-busybox commands did (was hoping to find a =
power-cycle option).

Going forward though, I have more packages to build and I verified the =
IP-KVM is working properly, so I can attempt to poke around if it =
happens again.

I did find this in the logs, it at least looks interesting:
