One more S3 cycle

It went to sleep again right away, even although button module was removed...

ls completes OK after a while...

What to do about the IDE issue?

I use acpid and power button to initiate S3 and remove button module before S3 
as it improves the situation on hardware which otherwhise ends up in an endless
S3 loop. What to do about the button issue?

Michael
