    Dear Communiy,

    I wish you a happy new year. I just discovered the community and hope my post in really related to Intel Graphic driver with Fedora 23.
    I am facing the following issue. Each time I try to read a video (regardless of the format), the complete X environment is crashing and rebooting with the following error extracted from dmesg :
     

    Code:
    [drm:intel_pipe_config_compare [i915]] *ERROR* mismatch in has_drrs (expected 1, found 0)

    It seems to be linked to Bug #808720 which is a regression in kernel 4.3 compare to 4.2. But from my understanding it should be fixed.

    I am running the following environment :

    Code:
    [root@localhost ~]# inxi
CPU~Dual core Intel Core i5-3337U (-HT-MCP-) speed/max~799/2700 MHz Kernel~4.3.3-300.fc23.x86_64 x86_64 Up~3 min Mem~1129.2/7548.9MB HDD~256.1GB(57.5% used) Procs~216 Client~Shell inxi~2.2.31

    with Mate 1.12.1
     

    Code:
    bash-4.3$ lspci

    I have no clue on how to solve it so far searching the web. Any ideas ?

    Thx

    Laurent
