The entries you pasted are after I turned the monitor back on. I took another pair of dumps now, one right after it turned off and another one after turning it back on, and the diff shows that the second "PCH HDCP audio interrupt" is output when the monitor has been turned on. The first one is when things start to go wrong.
so, soon after this the monitor is shut down [47763.079587] [drm:pch_irq_handler], PCH HDCP audio interrupt [47763.079611] [drm:i915_hotplug_work_func], running encoder hotplug functions . . and this comes after powering it back on (note the couple of seconds gap due to me being slow :) [47766.403771] [drm:pch_irq_handler], PCH HDCP audio interrupt [47766.403785] [drm:i915_hotplug_work_func], running encoder hotplug functions [47766.404715] [drm:intel_dp_check_link_status], TMDS-9: channel EQ not ok, retraining . . -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999539 Title: displayport monitor shuts off once in a while To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/999539/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
