The 'call doadump' must be failing, or something. The machine runs the disk like mad for hours, and never stops. I can't see the screen (acpi or something turned it off), otherwise I would tell you more. So, two questions: 1) How can I get it to leave my screen alone when suspending, so I can see what's happening on it's way back up during resume? 2) How can I get the debugger to use the serial port at this point? It works once I've booted up, etc, but when resuming the serial port never comes back alive. I have comconsole setup in my loader.conf, and that seems to switch the bootup and such, but once I try to resume, it kills the serial and the console keyboard so I have nothing.
