About "You need to restart your computer" (kernel panic) messages
UNIX-style operating systems (such as Mac OS X, Mac OS X Server, AIX, and A/UX) may experience a type of issue called a "kernel panic," which may provide information useful for software developers or troubleshooting. In Mac OS X 10.2 or later, the message that appears states "You need to restart your computer. Hold the Power button for several seconds or press the Restart button."Tip: Update to the latest versions of Mac OS X to avoid certain potential kernel panic situations.

PANIC(9) BSD Kernel Developer's Manual PANIC(9)NAME
panic -- Bring down system on fatal error
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
void
vpanic(const char *fmt, va_list ap);
void
panic(const char *fmt, ...);
DESCRIPTION
The panic() and vpanic() functions terminate the NetBSD system. The message fmt is a printf(3) style format string which is printed to the
console and saved in the variable panicstr for later retrieval via core dump inspection. A newline character is added at the end automati-
cally, and is thus not needed in the format string.
If a kernel debugger is installed, control is passed to it after the message is printed. If the kernel debugger is ddb(4), control may be
passed to it, depending on the value of ddb.onpanic. See options(4) for more details on setting ddb.onpanic. If control is not passed
through to ddb(4), a ddb(4)-specific function is used to print the kernel stack trace, and then control returns to panic().
If control remains in panic(), an attempt is made to save an image of system memory on the configured dump device.
If during the process of handling the panic, panic() is called again (from the filesystem synchronization routines, for example), the system
is rebooted immediately without synchronizing any filesystems.
panic() is meant to be used in situations where something unexpected has happened and it is difficult to recover the system to a stable
state, or in situations where proceeding might make the things worse, leading to data corruption/loss. It is not meant to be used in scenar-
ios where the system could easily ignore and/or isolate the condition/subsystem and proceed.
In general developers should try to reduce the number of panic() calls in the kernel to improve stability.
RETURN VALUES
The panic() function does not return.
