I had a
problem booting my 12" 867 MHz PowerBook G4 last week and it was temporarily solved by resetting the PMU. Now it's a few days later and... Same thing. This time, I didn't reset the PMU right away and after a few minutes, the screen went off-white and this message came up in ugly text:
Invalid memory access at %SRR0: 00014000 %SRR1: 01400000

I've heard of booting into Open Firmware before, but what exactly does it mean? Does that message at the very top about an "Invalid memory access" mean I have a bad stick of RAM? I have this machine maxed out and have since getting it back in July of last year. Could memory just go bad like that? I haven't dropped, kicked or abused this machine in any way. It gets relatively little use, actually and spends most of its time on a desk.
I'm running 10.3.2 with no ShapeShifter theme or other GUImod running and nothing unusual in my Menubar. Apps running during both incidents include: Palm Desktop, Mail, Safari and Konfabulator (with just 3 widgets open) and "Red Pill" as a screen saver. I'm not sure if the screen saver was activated when she fell asleep.
What now?
(BTW, I had a kernal panic on my 15" G4 iMac for only like the third time
ever this morning. What are my Macs trying to tell me)?
