Did it run?  Did it produce the correct results?  How fast was it?

Actually, this is good news (as long as it does not happen too often) -
it shows that you're trying new stuff.  We'll get the board back online
shortly.  In fact, there is a remote power-cycle feature in that setup,
but it turned out to be broken - chances are that it'll be fixed by next
time we need it. ;-)

Connecting to the USB UART port, which is configured as the serial
console in the Linux kernel, I got this one line of output:

7>[drm:output_poll_execute], <7>[drm:output_poll_execute], <7>[

This must be a previously buffered portion of the kernel's output.

No response to input from that serial port, indeed - the system is
locked up good.
