Hello,

I have installed Debian/stretch on a MacBook Pro, and it all seems OK, except suspend/resume is now suspend/crash instead. Sometimes I get a black screen, most times the screen gets restored and then it crashes.

Furthermore, I was accidentally pressing the power button and shutting down the system, so changed this action to suspend. Now instead of a clean shutdown, I get a dirty crash whenever I accidentally press the power button :-| Maybe should change that to ignore for now...

How do I go about debugging suspend/resume problems?

Online reports seem to indicate that there should be no problems with suspend/resume and a recent kernel.

Regards
