(hardware: Dell Latitude D810) S = successfull resume D = had to resume 2 times, that means when pressing the power button the LED goes from blinking to on and after a few seconds it goes back to blinking, but without a beep in between; after pressing the power button a second time resume is successfull F = resume failes, NO beep -run 1: D D F -run 2: D D D(some X garbadge) F -run 3: S S S S S S F -run 4: S S F -run 5: D F Very odd, nothing was changed in between and after each F i switched it off... because it was dead. With 2.6.19.7 i have never seen it fail.
