 This section explains what happens when the system crashes
 and (very briefly) how to analyze crash dumps.

 When the system crashes voluntarily it prints a message of the form

 on the console, takes a dump on a mass storage peripheral,
 and then invokes an automatic reboot procedure as
 described in
-.IR reboot (8).
+.Xr reboot 8 .
 (If auto-reboot is disabled on the front panel of the machine the system
 will simply halt at this point.)
 Unless some unexpected inconsistency is encountered in the state
 of the file systems due to hardware or software failure, the system
 will then resume multi-user operations.

 The system has a large number of internal consistency checks; if one
 of these fails, then it will panic with a very short message indicating

 the error, or a two-word description of the inconsistency.
 A full understanding of most panic messages requires perusal of the
 source code for the system.
-.PP
+.Pp
 The most common cause of system failures is hardware failure, which
 can reflect itself in different ways.  Here are the messages which
 are most likely, with some hints as to causes.
 Left unstated in all cases is the possibility that hardware or software
 error produced the message in some unexpected way.
-.TP
-.B iinit
+.Bl -tag -width 8n -compact
+.It iinit
 This cryptic panic message results from a failure to mount the root filesystem
 during the bootstrap process.
 Either the root filesystem has been corrupted,
 or the system is attempting to use the wrong device as root filesystem.
 Usually, an alternative copy of the system binary or an alternative root
 filesystem can be used to bring up the system to investigate.
-.TP
-.B Can't exec /sbin/init
+.It Can't exec /sbin/init
 This is not a panic message, as reboots are likely to be futile.
 Late in the bootstrap procedure, the system was unable to locate
 and execute the initialization process,
-.IR init (8).
+.Xr init 8 .
 The root filesystem is incorrect or has been corrupted, or the mode
 or type of /sbin/init forbids execution.
-.TP
-.B IO err in push
-.ns
-.TP
-.B hard IO err in swap
+.It IO err in push

 The system encountered an error trying to write to the paging device
 or an error in reading critical information from a disk drive.
 The offending disk should be fixed if it is broken or unreliable.

 These panic messages are among those that may be produced
 when filesystem inconsistencies are detected.
 The problem generally results from a failure to repair damaged filesystems
 after a crash, hardware failures, or other condition that should not
 normally occur.
 A filesystem check will normally correct the problem.
-.TP
-.B timeout table overflow
-.ns
+.It timeout table overflow
 This really shouldn't be a panic, but until the data structure
 involved is made to be extensible, running out of entries causes a crash.
 If this happens, make the timeout table bigger.

-.B KSP not valid

-.TP
-.B SBI fault
-.ns
-.TP
-.B CHM? in kernel

+.It SBI fault

 These indicate either a serious bug in the system or, more often,
 a glitch or failing hardware.
 If SBI faults recur, check out the hardware or call
 field service.  If the other faults recur, there is likely a bug somewhere
 in the system, although these can be caused by a flakey processor.
 Run processor microdiagnostics.

 and are printed on the console.

 The system initialization process has exited.  This is bad news, as no new
 users will then be able to log in.  Rebooting is the only fix, so the
 system just does it right away.

-.B out of mbufs: map full
+.It out of mbufs: map full
 The network has exhausted its private page map for network buffers.
 This usually indicates that buffers are being lost, and rather than
 allow the system to slowly degrade, it reboots immediately.
 The map may be made larger if necessary.

 That completes the list of panic types you are likely to see.
-.PP
+.Pp
 When the system crashes it writes (or at least attempts to write)
 an image of memory into the back end of the dump device,
 usually the same as the primary swap
 area.  After the system is rebooted, the program
-.IR savecore (8)
+.Xr savecore 8
 runs and preserves a copy of this core image and the current
 system in a specified directory for later perusal.  See
-.IR savecore (8)
+.Xr savecore 8
 for details.
-.PP
+.Pp
 To analyze a dump you should begin by running
-.IR adb (1)
+.Ic adb
 with the
-.B \-k
+.Fl k
 flag on the system load image and core dump.
 If the core image is the result of a panic,
 the panic message is printed.
 Normally the command
-``$c''
+.Dq $c
 will provide a stack trace from the point of
 the crash and this will provide a clue as to
 what went wrong.
