It's completely hosed: not possible to ssh, does not respond to ping either.

I made a quick test with netconsole. After booting with
no_console_suspend=1, and setting the netconsole parameters, I can get
kernel messages (to my android phone) when suspending the machine. But
no messages after the failed resume.

Hmm, might I be able to capture messages over USB serial port...?
