I don't know if this is relevant since consensus seems to be leaning
towards a RAM issue, but I suffered a kernel panic when my hard drive
got "too full," i.e., not leaving at least 10% empty, something I
didn't know not to do until it was too late. DiskWarrior was the
*only* thing that rescued my data. Luckily for me I got everything
back, promptly installed a bigger drive, and now run at never more than
80% of the capacity of the drive. I haven't had a kernel panic since.
FWIW, I had 1GB third-party RAM installed, up from the stock 256,
throughout the whole ordeal and through every system update (I'm
running 10.3.8 now).

Agreed. I was running for months with a cheap 512 chip added to my PB

chasing all kinds of stuff based on what was loading when it paniced,

it, had me shaking my head - it was *obvious* to me the upgraded os
was broken since the memory has been fine for months -- what are the
chances that my memory went south at precisely at the moment of
upgrade... )
Sure enough, the thing just booted up and ran flawlessly. Apparently,
the new os level is incredibly sensitive to memory quality. (probably
a feature added by the high end memory makers - since we are
entertaining conspiracy theories on gbooks.)
I thought it was the uplift to 10.3 that did this, but its been a
while. Might have been 10.2.

My first time having to deal with this, I'd love some assistance.
I have an old 466MHz SE Graphite iBook (the clamshell one). I had
10.1.5 up on the machine and yesterday tried to upgrade to 10.2. The
upgrade went through well apparently until time to reboot. Now it
"kernel panics".
Following Apple's documentation, I've reset NVRAM & PRAM and tried to
boot from the Mac OS X.2 install disc. When this happens, it boots to
the gray apple, then I get video problems (once an overly bright
screen wash, once lots of verticle gray lines) and a freeze. A soft
restart is possible (Apple-ctrl-Power), so I've not reset the PMU.
Reseat your RAM, possibly replace it...such kernel panics are usually
related to poor ram. (although if you had OS 10.1 installed it should
have given you hassles before.)
It could also well be a munged upgrade. Try resetting the PRAM three or
four times in a row (hold down control-alt-p-r until it bongs that many
times. Some people recommend ten times for particularly resilient NVRAM
resets)
