  • So I've been getting this odd problem where during certain graphically intensive situations, X completely goes down and I can't get it back up by restarting it by dropping into the terminal. Today I finally got a message come through on dmesg and I captured it finally!

    I am looking for help on who to talk to and/or possible solutions for what I'm experiencing. To help whomever is nice enough to read this and look into it I'm including my inxi output as well as the dmesg of the error.

    Inxi output :

    System:    Host: mordecaipc Kernel: 3.9-5.dmz.1-liquorix-amd64 x86_64 (64 bit, gcc: 4.7.3)

    and here's the dmesg error log:

    [drm:i915_reset] *ERROR* GPU hanging too fast, declaring wedged!
    [drm:i915_reset] *ERROR* Failed to reset chip.

    I don't think the bit about the ipv6 error has anything to do with it but I included it for completeness.

    Thank you in advance to anyone who spends any time on this. I really do appreciate it. I've scoured the Internet for several hours about this and I haven't found much that has been useful yet.

  • Hi Aaron, 

    could you please check if this is a rc6 related issue by booting your kernel disabling rc6 with this flag:


    There are known unsolved rc6 related hungs.
