Version-Release number of selected component (if applicable):
Build : RHEL-7.0-20131111.1
Steps to Reproduce:
1. obtain a box with DVI output and as much screens that you device supports
2. if you need signal splitter use it as well
1. connect as much screens as supported to the box
2. perform several suspend/resume cycles
On resume system hangs with no video/ssh/numlock.
Screens should be correctly set, their native resolution should be set and
suspend/resume cycles should work as well
You need linux-firmware >= 20131106-0.1.git7d0c7a8
This need to be retested but here i can not reproduce with :
We believe this is already fixed but moving to 7.1
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.
This is fixed, there is a new (previously undiscoverable) mild bug on DVI as well as all outputs: https://bugzilla.redhat.com/show_bug.cgi?id=1263784
But this issue is fixed.
