.SH DESCRIPTION
.PP
.I Archreset
reboots the machine.
.PP
Depending on configuration settings, the platform-dependent
.I exit
might reboot the system.  If
.I ispanic
is set,
.I panic
is called.
.PP
.I Ndnr
(no deposit, no return)
disables all
interrupt sources and halts the current processor.
.PP
.I Panic
writes a message to the console and
causes the system to give up the ghost.
It disables interrupts, dumps the kernel stack,
and halts the current processor;
if more than one, others will gradually come to a halt.
A subsequent
.I panic
on a different processor will halt that processor with
.IR ndnr;
a recursive
.I panic
will reboot the machine with
.IR archreset.
.PP
The format
.I fmt
and associated arguments are the same as those for
.IR print (9).
.I Panic
adds a prefix
.L "panic: cpu\fIn\fP:"
and a trailing newline.
.SH "SEE ALSO"
.IR panic (9)
.SH BUGS
Note the differences with
.IR panic (9).
