[Bug 568005] Re: Screen shows grey bars after resuming from suspend

[databubble]

I did some further testing of using pm_suspend from tty1.  I noted that
the same behaviour occurred... that is that on the first, or second
attempt resuming worked... but then on subsequent attempts it did not
work, with the whole display going white, and then bleeding to black.

Noting this, I then tried simply running the following, repeated:

# vbetool dpms off; sleep 10; vbetool dpms on

On the fourth iteration the screen went white and bled to black.
Further iterations did not restore the screen.


The system was still responding fully.... I initiated a shutdown by pressing the power key.
