Disadvantage is that not all hardware will be completely reinitialized

Don't stop other CPUs on reboot. This can make reboot more reliable
in some cases.

Debugging
oops=panic Always panic on oopses. Default is to just kill the process,
but there is a small probability of deadlocking the machine.
This will also cause panics on machine check exceptions.
Useful together with panic=30 to trigger a reboot.
kstack=N Print that many words from the kernel stack in oops dumps.
Misc
noreplacement Don't replace instructions with more appropiate ones
for the CPU. This may be useful on asymmetric MP systems
where some CPU have less capabilities than the others.
