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.
