Summary: Onboard Intel GMA X4500HD fails to initialize under
3.16.x
Product: Drivers
Version: 2.5
Kernel Version: 3.16.1
Hardware: All
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Video(DRI - Intel)
Assignee: intel-gfx-bugs at lists.freedesktop.org

Created attachment 146771

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.
