Subject: [Bug 112781] New: radeon: f95429e "only init fbdev if we have connectors" breaks suspend on Clevo P170EM laptop

Bug ID: 112781
Summary: radeon: f95429e "only init fbdev if we have
connectors" breaks suspend on Clevo P170EM laptop
Product: Drivers
Version: 2.5
Kernel Version: 4.5-rc2
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Video(DRI - non Intel)
Assignee: drivers_video-dri@kernel-bugs.osdl.org
Reporter: haagch.christoph@googlemail.com

dmesg
On a Clevo P170EM with these GPUs:
00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor
Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI]
Wimbledon XT [Radeon HD 7970M] (rev ff)
With rc2 suspend stopped working. It starts to suspend, turns off the display,
etc., but then it fails to actually enter the suspend state. The power stays on
and after a while the radeon GPU fan starts spinning up. There's nothing in the
logs relating to the problem I could find.
I bisected to f95429eccc570dc45d589c327bfcfddcdc3e8228 and confirmed it with
latest linux git (4.5-rc5) with this commit reverted - suspend works. Attached
is a dmesg with this setup including one successful suspend and wake up.
