mplayer and vlc stopped showing video while trying watch .flv, .mp4,
etc. on my FreeBSD laptop running:

  FreeBSD peace 10.1-STABLE FreeBSD 10.1-STABLE #7 r284146: Mon 
  Jun  8 05:10:48 CDT 2015     root@peace:/usr/obj/usr/src/sys/PEACE  
  i386

I get a black screen. However, audio works fine. I used to be able to 
be able to do this before. Looking at Xorg.0.log, I see:

  [    35.523] (EE) intel(0): Detected a hung GPU, disabling acceleration.


dmesg shows:

  info: [drm] Initialized i915 1.6.0 20080730 for drmn0 on minor 0
  error: [drm:pid12:i915_hangcheck_hung] *ERROR* Hangcheck timer
  elapsed... GPU hung


I have the following graphics chip:

  vgapci1@pci0:0:2:1:     class=0x038000 card=0x201a17aa chip=0x27a68086 rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller'
    class      = display


Using the x11 driver works, but can't scale to fullscreen.

Xorg.0.log, dmesg and i915_error_state is at:

Anybody else having similar issues?  Any ideas/suggestions will be
greatly appreciated.
