Dear Maintainer,

Sometimes, when I resume from suspend, I get these 2 errors in my logs:
June 16 14:35:07 myhost kernel: Suspending console(s) (use no_console_suspend to debug)
-> June 16 14:35:07 myhost kernel: [drm:hsw_unclaimed_reg_clear] *ERROR* Unknown unclaimed register befor
-> June 16 14:35:07 myhost kernel: [drm:hsw_unclaimed_reg_check] *ERROR* Unclaimed write to c7204
June 16 14:35:07 myhost kernel: Restarting tasks ... done.
 
Soon after that, my screen turns on/off intermittently, especially if
I use software in full screen (Firefox, LibreOffice, URXVT etc.)
 
When it turns off, I usually get some (2-4) of these warnings:

look like you have already the latest BIOS. So please, attached full dmesg with drm.debug=14 in boot command line where you are reproducing this issue.

Created attachment 124929 [details]
New logs with drm.debug=14

Took me about 5 suspend/resume actions to replicate it this time. Before doing the 5'th suspend, I waited for DPMS to turn off my display, and then pressed some keys to get my screen back to normal, then I suspended the system. So, I think it might be related to DPMS somehow.

Like I said; upon resume, the screen blanking only happens in FULL-SCREEN software, and it only seems to go away if I return the windows to their normal size, using some key combo, or if I use my Dell's pointing stick.

Any news on this one guys?

Comment 5 Imre Deak 2016-09-27 12:24:23 UTC

Could you try the drm-intel-nightly branch from
git://anongit.freedesktop.org/drm-intel ?

Comment 6 Jari Tahvanainen 2017-03-28 14:04:10 UTC

kolp23@yopmail.com - We seem to have neglected the bug quite a bit, apologies. Do you see this problem with the latest kernel (preferable drm-tip branch from
git://anongit.freedesktop.org/drm-tip) ?

Mark this as 
REOPENED if you can reproduce (and attach kernel log) and 
RESOLVED if you cannot reproduce.

based on the lack of activity in recent times this bug will be closed but if the issue is again visible with latest configuration open a new bug
