Hi,

This just happened to me:

X appeared to have stopped rendering (or nothing goes through), but the
applications worked fine (I still had sound from a video). My video
card is:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
        Subsystem: Lenovo Device 21d0
        Flags: bus master, fast devsel, latency 0, IRQ 43
        Memory at f1400000 (64-bit, non-prefetchable) [size=4M]
        Memory at e0000000 (64-bit, prefetchable) [size=256M]
        I/O ports at 6000 [size=64]
        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

I was able to switch to the terminal and reboot.

I suspect this is new in 3.16 and I've noticed some other oddities
since I upgraded from 3.15.8:
 * when adjusting the screen brightness, the minimum setting is now
   "LCD off";
 * when watching a video in fullscreen, I can see a flicker every 10s
   or so.

Thanks,

If you can reproduce this somehow, please boot with drm.debug=0xe and
attach the complete dmesg up to the WARNING. We seem to loose track of
pageflips under obscure circumstances sometimes. We have more band-aids
queued up, but fixing the underlying issue would be better ofc.

Thanks, Daniel

I don't know how to reproduce it, but I've added the option to my
kernel command line. It does not seem to introduce any noticeable
performance degradation so I'll keep it on until the issue reappears.
