Ok, this _may_ have been the bug with the kernel wait queues that was fixed
in .15 (and that then resulted in the other problems showing up). I certainly
hope that .17 is stable again (despite one report of problems with ppp -
maybe module recompile time).

There are a few files in linux/Documentation about this: BUG-HUNTING,
oops-tracing.txt. They by no means teach you to find the bugs, but they
might be helpful if you have a vague idea about it from before and just
want to get some ideas.
