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’ing 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:
