Bug ID: 117931 Summary: Black screen after resume from hibernate on HP Pavilion dv7 with 2 AMD GPUs Product: Drivers Version: 2.5 Kernel Version: 4.6-rc5 (mainline), 3.14.53, 4.4.7, 4.4.8 (Fedora) Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: eugene.shatokhin@rosalab.ru Regression: No
Created attachment 215701 --> https://bugzilla.kernel.org/attachment.cgi?id=215701&action=edit The system log from Fedora 23 after resume. drm.debug=0x1e was set, just in case
When the laptop resumes from hibernate, there is no output on the screen. In some cases, I can connect to the machine via SSH after that, so I can see that the system does not crash. Looks like it is just graphics that is not turned on.
The system uses 'radeon' driver.
Laptop: HP Pavilion dv7 with A8-3530MX APU Two graphics cards: * Radeon HD 7690M (pci:1002-6741-103c-1860) * Radeon HD 6620G (pci:1002-9641-103c-1860) More hardware info for that system: http://linux-hardware.org/index.php?probe=4c12fda921
OS, kernel: I tried both ROSA R7 x86_64 with kernels 4.6-rc5 (mainline), 4.4.7, 4.1.22 and Fedora 23 with kernel 4.4.8-300.fc23.x86_64. The problem showed up with each of these.
The log below is from Fedora where I was able to connect to the machine via SSH after the problem happened.
Resuming from suspend-to-RAM works fine though.
I also tried kernel 4.1.x with the proprietary fglrx driver (v.15.201.1151) instead of 'radeon' - the graphics worked OK after resume from hibernate this time.

--- Comment #3 from Eugene A. Shatokhin eugene.shatokhin@rosalab.ru --- Re-checked on Fedora 23 x64 with the mainline kernel 4.7-rc7, git rev 68093c43f352, with no additional patches.
Resume from hibernation is not fully working yet but the problem looks different this time.
When I put the system to suspend-to-disk then try to resume it, the desktop environment appears this time but does not respond to keyboard, mouse, whatever.
The system log contains lots of meesages "radeon: The kernel rejected CS, see dmesg for more information.".
Xorg.0.log ends with the following: [ 1608.239] (WW) RADEON(0): radeon_dri2_flip_event_handler: Pageflip completion event has impossible msc 78924 < target_msc 78925
I will attach the logs below.
Besides, after I have done suspend-to-ram and resumed the system (without prior reboot after the problem happened), the desktop seemed to be operational again after a couple minutes.
Interestingly enough, lspci shows incomplete info for one of the GPUs this time (was OK with the earlier kernels): ------------------- 01:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Whistler [Radeon HD 6630M/6650M/6750M/7670M/7690M] [1002:6741] (rev ff) (prog-if ff) !!! Unknown header type 7f Kernel driver in use: radeon Kernel modules: radeon ------------------- May be it is not related to the problem, may be it is.
