intel_display_power_put+0x14c/0x160 [i915]()
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: DRM/Intel
Assignee: intel-gfx-bugs at lists.freedesktop.org
Reporter: philipp at redfish-solutions.com

This is seen on Fedora 21 with:
xorg-x11-drv-intel-2.99.916-3.20141117.fc21.src.rpm
on a Dell Latitude E5540 with BIOS A04 (01/22/2014), and kernel:
3.18.7-200.fc21.x86_64
On an idle laptop with no docking station, while it tries to go into partial
energy conservation (shutting down the display), the following oops is seen.
This is also seen on a docking station with a DVI-connected monitor.
