Yeah, there is some problem with SATA resume. It would be beautiful if 
the people who actually see this could narrow it down with bisection. 
"It works for me" is clearly the case for many people, but not all.

Thomas found a new twist to this today: applying the patch below (which 
turns on ATA_DEBUG) made the SATA problem go away on his laptop. 
Michael, could you try this patch, does it change the behavior of your 
laptop in any way?
