Exact same error message in brand new Dell Latitude e5550 (Intel HD 5500), BUT: 1) No external monitors 2) The laptop won't BOOT, execution hangs up.
Both in 4.2.0-27 amd64 and 4.2.0-16 amd64. After some reboots it will hang up at "Started Gnome Display Manager" Booting in recovery mode I find in dmesg: "snd_hda_intel 0000:00:03:0: failed to add i915 component master (-19)" Installing 4.5-rc4-wily gives me: "possible missing firmware /lib/firmware/i915/skl_guc_ver4.bin for module 915" and booting it "error parsing PCC subspaces from PCCT" boot hangs up again -- 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)!"
