If it's > not completely dead, then you might be able to ssh into it. 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...? -Tommi
