Pardon me piping up from the peanut gallery ...

Do we have a clear picture of the hardware/software combination this bug
is triggered by?

In particular:

- only tibook? What about iBook or later (Al-) PowerBooks?

- running pbbuttonsd (version?), no pmud present?

- running pmud (version?), no pbbuttonsd present?

- running pmud (version?) with pbbuttonsd in pmud-compat mode?
  (for this one you'll need to build your own pbbuttonsd, or ask me for
  such a beast)

- running neither of them?

- running some version of mouseemu?

- are you using either pbbuttonsd or mouseemu to block the trackpad while

That would help to narrow it down to either PMU or eventdev communication.
So far, I've not been able to get a clear picture from the reports. ISTR
one user reported that problems went away after using pmud/mouseemu
instead of pbbuttonsd, that's why I suggest testing the above
We've been bouncing a few ideas around WRT interaction between events and
PMU but that didn't help much.

If we can get a clearer picture about what usage pattern tends to
interfere with PMU/host communication, or generally locks out interrupts,
we could ask more specific questions on LKML.
