2.6.5/iBook G3: Oops on resume from sleep

[Aaron Lunansky]

So what I've figured out so far is that the system is not crashed- the
screen is still on in fact, blinking a cursor in the top left. I can ssh
in to the machine but a cursory review of dmesg shows nothing of
significance.

Unfortunately I can't do much with an ssh session before it seems to lock up,
but I can launch another ssh session if I want. Also, if I disconnect my
USB keyboard while the screen is in this blinking state, I get a "USB
device soandso" disconnected message.

Since my machines not crashing I can poke at it some more, but I could
use some pointers as to where I should poke.

Thanks,
Aaron
