Description Martin Steigerwald 2016-12-01 08:20:24 UTC
I am just reporting this as a separate bug, but it may be a duplicate of #98747, #98794, #98860, #98891, #98288 and probably more. But I am not sure whether it is, and kernel log asks me to file a _new_ bug, so reporting as new bug.

I got this with 4.9.0-rc4-tp520-drm-intel-fixes-btrfstrim which is a rc4 with drm-intel-fixes branch from 8th of November, I didn´t retest with 4.9-rc7 yet as I am back at 4.8 again after having faced a GPU hang on resume after hibernation, thats #98288.

Nov  8 21:19:08 merkaba kernel: [ 8401.004947] drm/i915: Resetting chip after gpu hang

Unfortunately I do not have a crash dump. As the hang was so long (or repeated) that I just switched off the machine with the power button.

I may retest with latest 4.9 kernel on the weekend, but not during the week anymore, but even then I cannot guarentee whether I can get a crash dump as when the machine is hanging, hmmm, maybe via ssh from another laptop.
Comment 1 Mark Janes 2016-12-07 18:02:02 UTC
Martin,  please verify that you can reproduce this using the modesetting DDX.  There are known issues with xf86-video-intel:


Section "Device"
    Identifier  "Intel Graphics"
    Driver      "modesetting"
    Option      "AccelMethod"    "glamor"
    Option      "DRI"            "3"
Comment 2 Martin Steigerwald 2016-12-07 20:42:42 UTC
Debian Sid switched to modesetting DDX by default a while ago, but I also used it before that time already.

Comment 3 Martin Steigerwald 2017-06-01 10:36:40 UTC
Closing, as I do not see this with recent 4.9 and 4.10 kernels, anymore. At least not with 4.9.24 and 4.10.16, but probably also some earlier versions.
