[Intel-gfx] DP1 Monitor Flashes

[Robert Navarro]

I too am having the same issue. I'm running on kernel 3.12.6 (just updated)

The issue happens less frequently, but it still happens and it's quite
annoying.

Previously I would just get lines like this:

[  342.071567] [drm:ilk_display_irq_handler], Pipe B FIFO underrun
[  342.071584] [drm:cpt_serr_int_handler], PCH transcoder B FIFO underrun

But after the recent kernel update it looks like there are some more debug
messages being sent out like this:

[  624.430107] [drm:i915_driver_open],
[  624.439972] [drm:i915_gem_context_create_ioctl], HW context 1 created
[  624.450177] [drm:i915_gem_context_destroy_ioctl], HW context 1 destroyed

I have a bug open for this, but I haven't heard a response on next steps
unfortunately :(
