It's not really solved, it's a workaround that makes the machine use more power. Let's hope that anyone can get intel to fix this? I am trying to contact people at intel and Canonical to pick this up. Let's hope someone will act.

The hangs occur between minutes and hours after booting and there is no information found related to them in kernel message buffer. I found the above commit by doing bisection between 4.1.0 and 4.2-rc1 and reported it to intel-gfx mailing list: http://lists.freedesktop.org/archives/intel- gfx/2016-January/084203.html I tested that these hangs occur with 14.04 LTS using latest linux-generic-lts-wily (4.2.0-23-generic) kernel exactly as with any kernel beginning from 4.2-rc1 up to 4.4-rc8. I'm now writing this bug report running 4.4-rc8 with patches from the above commit removed because 4.2.0-23-generic just hanged while I was trying to send report. --- ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: jamse 2144 F.... pulseaudio CurrentDesktop: Unity CurrentDmesg: [ 20.017300] init: plymouth-upstart-bridge main process (1462) terminated with status 1 [ 20.017332] init: plymouth-upstart-bridge main process ended, respawning DistroRelease: Ubuntu 14.04 EcryptfsInUse: Yes InstallationDate: Installed on 2014-11-17 (415 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64 (20140722.2) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 04ca:3010 Lite-On Technology Corp.
