A last-chance kernel message dumperA last-chance kernel message dumperPosted Nov 28, 2003 19:00 UTC (Fri) by giraffedata (subscriber, #1954)Parent article: A last-chance kernel message dumper I'm glad someone is attacking this problem. I find that transcribing the stack trace by hand is the least of the problem. Often, the system crashed some time ago and the video controller has gone to sleep. (The screen is blank). Since the system is dead, you can't wake it up. I won't be using this kernel message dumper, though -- it isn't useful enough. A magic sysrq function that works after the system has panicked and dumps the kernel message buffer to a floppy would be nice, though. Or maybe something that dumps it at panic time to a predesignated fixed disk location).
