Calls to panic in the kernel.

Lars pointed out that there are over 1200 calls to panic() in the kernel.

A panic which shouldn't happen gives programmers the opportunity to write a message which should (almost) never see the light of day. Some examples:

From drivers/message/fusion/mptlan.c:

panic("Damn it Jim! I'm a doctor, not a programmer! "
                "Oh, wait a sec, I am a programmer. "
                "And, who's Jim?!?!\n"
                "Arrgghh! We've done it again!\n");

From drivers/scsi/aha1542.c:

panic("Foooooooood fight!");

In the recent past, kernel/suspend.c had this:

if (pos%PAGE_SIZE) panic("Sorry, dave, I can't let you do that!\n");
