Re: Powerbook shuts down hard when hot, patch found

This all smells to me like a silicon bug, so I'd start searching
in the silicon erratas. But I'm not sure, of course. It's also strange
that it depends on temperature. (That's why I first expected the PMU
would cause this).

Thanks for your help.

Could be that we are creating a short by driving the output low, thus
causing the silicon to heat up, but that's strange.

Also, the other change I made you do turns these into inputs, thus the
DDL lines should be pulled up, unless ... the board doesn't have
pullups.
