Comment # 37
on bug 105018
from L.S.S.
Attempted to lock the screen and leave it blank for a while to see what
happens, and it seems for the first time there are still errors related to
VBLANK, but they appear minor as the system woke up just fine.
I tried letting the screen blank twice this time, and the errors did not show
up the second time. Only during first time did the errors appear, though this
is probably not enough to prove much. But still, I don't see that kernel bug
this time so that must have been fixed.
I'm yet to assess whether the bug can no longer be reproduced as I've been
avoiding having to leave the screen blank, as back then this bug has caused
losses of unsaved work and other problems due to the crash.
