Re: powerbook hang from post-sleep cdrom access - fix

Aye. Can you be more specific about 'do whatever needs to be done'? Can I
just send the disk a read command to wake it up? Send a reset
command?? Will a reset command hurt if I always send a drive reset
there?

My expirience is that just reading the drive causes a problem, much like
userspace trying to read it.  there is also the door locking feature that I
suppose could be done explicitly on wakeup if mounted.  I dont know what else a
"media change" ctl entails, but it seems to do enough to get the cdrom back to
where it left off.

OK, that seems to mean wherever we can safely send the drive a reset
command after sleep, we should do that. Now under what conditions will a
reset command mess up things beyond recovery? Is it possible to sleep the
machine while the IDE drive has a request under service?
