Hi
This commit ( a4de05268e674e8ed31df6348269e22d6c6a1803 ) hangs my boot with 3.16-git. Reverting it lets the boot proceed.
I have an i7 with a built-in i915 and an pcie r7 260x. The R7 is the primary console. The i915 is initialized
but does not have a physical display attached.
With the patch applied the boot stops at the messages:
[drm] Memory usable by graphics device = 2048M
[drm] Replacing VGA console driver
and I need to interrupt or power off the box to get it back.
(I did not notice messages about the R7 but they could have easily been missed - this box does not have a serial console)
Without the patch I get:
