This bug makes my Dell Latitude laptop shutdown (power off). In that bug report I provided a lot of information about my system, logs and tests I did. Currently, only kernel "3.13.0-36-generic" running module "/lib/modules/3.13.0-36-generic/kernel/ubuntu/i915/i915_bdw.ko" doesn't have this bug. Hence, this bug is far from "solved" and shutting up dmesg definitely won't solve it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"
