Yeah, I know..but I spent all day hacking .34 enough to
run lockdep and get those backtraces..and they *might* be
valid.  There's a small chance someone else has seen similar
things but not reported it for whatever reason, so maybe
they will chime in.

And finally, I will attempt to reproduce with some official
kernels, and will report what I find one way or another.

The .34 kernel has been a real bitch to get stable  (You
know things must be bad when my name's on -stable patches),
so I wouldn't be surprised if I'm hitting another real bug.

Thanks,
Ben
