Been able to test the patch. Some issues:
- when sleeping by closing the lid, and wakeing by opening again, laptop
resumes, then re-sleeps, then resumes again. Does not happen when using
- After wakeup, hard drive access seems to crash stuff hard (tested
while in X, everything goes fine until I tried to open a
second gnome-terminal: window appeared then it froze). Did another test
while in console, sleeping, wakeing, running hdparm -tT /dev/hda
resulted in a big trace which I photographed:
Like any talented dog, it can do flips.
Like any talented cow, it can do precision bitmap alignment.
