Hi,
I noticed a few crashes on this PowerBook G4 lately, starting somewhere in 3.2.0-rc1. The crashes are really rare and as I'm not on the system all the time I did not notice most of them. By the time I did, the screen was blank already and I had to hard-reset the box. But not this time:

When the crash occured, the system was failry loaded (CPU and disk I/O wise), so that may have triggered it. I tried to type off the stack trace, I hope there are not too many typos, see below.
The machine is fairly old, so maybe it's "just" bad RAM or something, I wouldn't be suprised. But maybe not, the box us pretty stable most of the time and only now I notice these rare crashes.
If anyone could take a quick look...?
Thank you, Christian.
