I'm making some progress on the Intel crashes using dtrace probes. The proximate cause seems to be that graphics driver code is trying to access a "resource" after it's been deleted. The "resource" is being deleted from user mode, so this *might* be a Firefox bug. It may be tricky to find out for sure, though. Dtrace is being a pain -- I can't get it to symbolicate user-mode stacks, though it's supposed to (and often does).

Dtrace is being a pain -- I can't get it to symbolicate user-mode stacks, though it's supposed to (and often does). I've been testing with a local build without symbols stripped. Next I'll try with a tryserver build with the same characteristics.
