force linux reboot when "Input output error"

$reboot
bash: /sbin/reboot: Input/output error

$shutdown -r now
bash: /sbin/shutdown: Input/output error

#
# if the above reboot commands doesn't work try either forced reboot or shutdown
#

# force reboot
$echo 1 > /proc/sys/kernel/sysrq
$echo b > /proc/sysrq-trigger

# force shutdown
$echo 1 > /proc/sys/kernel/sysrq
$echo o > /proc/sysrq-trigger

#
# this basically does the same as REISUB (just the reboot part, the B), it reboots immediatelly

This is great, it will help me while I figure out why Arch has some weird I/O errors that force me to shutdown with the server button. Thanks a lot!
