Is there any way to force an immediate reboot as if to push the reset button in software? Got a remote server that i need to reboot and shutdown isn't working.If it has Oopsed, and the "reboot" command does not work, then all bets
are off - kernel memory has probably been corrupted.
Get one of those powerstrips that you can telnet into and power cycle
things remotely.
If it has sysrq compiled in as root just do:
echo s > /proc/sysrq-trigger
echo u > /proc/sysre-trigger
echo s > /proc/sysrq-trigger
echo b > /proc/sysrq-trigger
This will "sync", "umount/remount read-only", "sync", "immediate hardware reboot". Should always work...
