Yes It is still an issue , with slight changes
Bug description:
General BUG Description: Suspend works, resumes but screen always remains black
with no cursor
Hibernation always throws acpi errors; sometimes, after repeated
tries to turn off HDD, it succeeds
Other times, hibernate can't turn off HDD and cut power completely
to screen, so I keep pressing the power
button until shutdown. After, if I press the power button, it
resumes normally.
