I need this patch to survive suspend on my powerbook, if the drive is sleeping when suspend is entered. Otherwise it freezes on resume when it tries to read from the drive.

Hello,
unfortunately, with this patch the disk always wakes up when resuming (from ACPI S1), even if it does not need to.
Could it be possible, to get previous behaviour, that is keeping disk sleeping when resuming?
Kind regards, Peter

We can probably kill the patch completely, I'm not so sure the missing idle command was the reason for the drive hang. But my problematic case was resuming with a previously suspended drive, so...
