I've just started getting this after updating to linux- image-3.19.0-30-generic from linux-image-3.19.0-28-generic.
NUC 5i3RYH connected via the mini-hdmi port to a 720p tv. 100% repeatable for me using Kodi 15.1. If I play a video I get audio, but the video is all black. If I activate the on-screen display items they render fine, but the video content itself is missing. Audio is fine. Entering and exiting a video I get this each time: [ 29.275053] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! [ 29.275763] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! [ 29.316539] sound hdaudioC0D0: HDMI: ELD buf size is 0, force 128 [ 29.316579] sound hdaudioC0D0: HDMI: invalid ELD data byte 0 [ 29.348980] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! [ 29.363813] [drm:gen8_irq_handler [i915_bpo]] *ERROR* The master control interrupt lied (SDE)! Always the first six lines, sometimes more of the (SDE!) lines follow. Always one set when playback begins, and another when playback ends. Further to this, if I disable VAAPI acceleration in Kodi, the video playback works again, but the kernel messages still appear. Both the black-video and the messages are completely new in 3.19.0-30 - haven't seen either in earlier kernels. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1488719 Title: dmesg shows "[drm:gen8_irq_handler [i915]] *ERROR* The master control interrupt lied (SDE)!"
