update, March 8, 2006: Still no panics since the RAM replacement. I think it's fixed.
update, January 17, 2006: I took the Powerbook in to have it serviced at the Apple Store at University Village in Seattle. They couldn't find anything wrong with it after having it for more than a week. A very surly worker there suggested replacing the RAM, which they did, and I haven't had a panic since. That's about 17 days panic free, so far; this is the longest free stretch since I started having panincs regularly, so I'm cautiously hopeful that this fixed the problem. I've even noticed fewer plain-old crashes (none!), so that gives me hope as well.
In September 2005, my Apple Powerbook G4 starting having fairly frequent kernel panics. As of November 2005, they're still happening, even after completely erasing the hard drive and reinstalling the OS. Yet, hardware tests have turned up nothing. I am posting my kernel panic logs here to make it easier for me to ask others to take a look and provide advice, and as a backup.
My current setup is Mac OS 10.4.3, 1 GHz PowerPC G4, 1 MB L3 cache, 512 MB SDRAM. No external devices connected.
The logs are listed oldest to newest, followed by kpdecode results for the most recent panics.
I only have the log entries for panics after the last erase and install.
If anyone has any idea what the cause of these panics is, or what a reasonable next step would be, I'd love to hear it. Please email me at doctormatt (a t) madandmoonly (d o t) com
