A kernel panic occurs when the kernel encounters a situtation that it
does not know how to handle. It is explictely invoked by the
``panic()'' function call within the kernel itself. It appears
in roughly 1,000 places in the 2.4.20 kernel.
For example, if a bogus interrupt is ever received, then irq.c will
panic the kernel. There are lots of opportunities to panic your
kernel. Hours of fun for the whole family!

Yeah.

When your index isn't current.

locate and find should take care of all your needs.

It's ``frozen'' when it doesn't respond or do what you think it should
be doing.
Use kill [pid]. If the SIGTERM handler for the process isn't
playing nice, then kill -9 [pid].
