Well I got a hold of the necessary cabling and I'm sorry to report that there is absolutely nothing on the serial console - I get the boot messages, etc. fine, the last message before crashing is 'Loglevel set to 9' [invoked by hand via Alt+SysRq+9], after which I crash it with 'strace ls -lR /' (as a normal user) and nothing else shows up, no oops no nada. After it crashed I attempted different Alt+SysRq combos (H/T/M/P/S/U) with no effect as well - even the help didn't show. This is still via the keyboard (not sure how to send a sysrq via serial), although I'm almost sure now that it wouldn't help - the system is just plain totally and completely dead, even the system bios is likely dead - including the System Management Mode code (likely responsible for lighting up the LED on fn key press/release, which no longer works [although not on every crash]). Cheers, MaZe.
