Panic
writes a message to the console and
causes the system to give up the ghost.
It enables interrupts, dumps the kernel stack,
and halts the current processor;
if more than one, others will gradually come to a halt.
Depending on configuration settings, the platform-dependent
exit
might reboot the system.
The format
fmt
and associated arguments are the same as those for
print(10.2).
Panic
adds a prefix
panic:
and a trailing newline.
