Subject: Re: [OpenAFS] Reproducible kernel panic on MacOS x 10.3.9 with 1.3.81

The kernel panic is clearly in the afs extension, according to the PC counter in the panic log and the kextstat command. The kernel panic I get is

This one's known but I'd been unable to figure out what was going on. I assume this happens when you're otherwise rebooting?

Rebooting or shutting down. Before 1.3.81, I would occasionally get kernel panics at runtime, but no longer; on the other hand, I don't leave my machine up long enough to necessarily reach that point. I reboot because AFS starts behaving strangely; I'll get contents of files that are incorrect, etc. I've used afs flushvolume at least once to fix that, but I don't know whether it's a consistent fix. In some cases, I've know that AFS had confused my machine because I'd get a bus error running gcc; I wish I recalled whether it happened only when compiling from source files in AFS space, or whether it was any invocation of gcc. That part isn't particularly reproducible, and I haven't until recently gotten fed up enough to commit myself to really tracking this problem down.
