No network, no console.. I saw "==========================================================================" on the console.. nothing after that. Would not respond to sysrq-t or any other sysrq combination other than -b, which rebooted the box. No output on netconsole at all, I had to walk to the other building to look at the monitor and reboot it. The second attempt jammed netconsole again, but I managed to get this from an ssh session I already had established. The machine died a slow and horrible death, but remained interactive enough for me to reboot it with echo b > /proc/sysrq-trigger Nothing else worked.
