I have an iBook G4 running stock 512MB memory. Last week I updated to 10.4.11 and immediately after it restarted, I kept getting recurring kernel panics. No rhyme or reason, it would occur randomly. It even occurred a couple of times at the login screen.
So, thinking I had a problem, and since I was planning on installing Leopard anyway, I popped in the install disk and did a disk utility check. Found some errors on the drive, and I told it to repair. I then proceeded to install Leopard by zeroing out the drive and installing fresh.
After installation completed, and running Leopard for not even 10 minutes I was greeted with a kernel panic. Now I get them periodically. Sometimes I'll get 4 or 5 in the span of half an hour. Other times I can use it for hours without issue. Disk utility says everything is kosher, so I'm not sure what to do next. I thought it was a software problem, but doesn't seem to be.
Below is my panic log. I would appreciate any help or guidance.
Thanks in advance! I don't have Apple Care and if it's a failed hardware component, I'm not sure I could afford to replace it. Definitely not the logic board. Suggestions to that end are sought as well.
