Created attachment 146771 [details] dmesg with debugging enabled Upon updating to 3.16.1, I see the following in my dmesg accompanied by a black monitor. The only solution is to reboot. Unfortunately, the bug does not occur on every boot. Seems to occur about 10 % of the time. I have enabled debugging by creating /etc/modprobe.d/i915.conf which contains a single line, "options drm debug=0xe" and attached the output of dmesg with that enabled. Note - my initramfs does not have i915 compiled in if that is important. Glad to provide additional details. % lspci -v 00:02.0 VGA compatible controller: Intel Corporation 4 Series Chipset Integrated Graphics Controller (rev 03) (prog-if 00 [VGA controller]) Subsystem: Gigabyte Technology Co., Ltd GA-EG45M-DS2H Mainboard Flags: bus master, fast devsel, latency 0, IRQ 47 Memory at fd800000 (64-bit, non-prefetchable) [size=4M] Memory at d0000000 (64-bit, prefetchable) [size=256M] I/O ports at ff00 [size=8] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915 Kernel modules: i915 Other users are affected by this as well[1], 1. https://bbs.archlinux.org/viewtopic.php?id=185650
I should have added to my initial report that the dmesg output I attached is with the system booting to the non-graphical login prompt. If I start X after that error is thrown, here is output of dmesg. ...

I have the same problem. I get this in dmesg: [ 12.413399] [drm:i915_gem_init] *ERROR* Failed to initialize GPU, declaring it wedged OpenGL is broken. Xv is also broken.

This particular ducttape-fix from Comment 8 is included in 3.16.4: See https://www.kernel.org/pub/linux/kernel/v3.x/ChangeLog-3.16.4 But, Jani, it's no duplicate of https://bugs.freedesktop.org/show_bug.cgi?id=76554.
