No HW acceleration with Intel integrated gpu on 10.2

Hello,

As the title says, I couldn't get hardware acceleration to work with my Intel GMA 4500 on 10.2. After being out of things to try, I decided to downgrade to 10.1, and then it worked.

Is this a known/unknown bug in 10.2, or were there changes on how you're supposed to configure this sort of thing?

Here is the relevant Xorg.0.log,

dmesg,

http://pastebin.com/jd5tUsaJ

and the relevant bit in pciconf

Code: 
vgapci0@pci0:0:2:0:   class=0x030000 card=0x04201028 chip=0x2e128086 rev=0x03 hdr=0x00
  vendor  = 'Intel Corporation'
  device  = '4 Series Chipset Integrated Graphics Controller'
  class  = display
  subclass  = VGA
 
If it works on 10.1 it should also work on 10.2. Your Xorg.0.log shows it's working, so far so good. However, your dmesg(8) shows some interesting errors:
Code: 
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
info: [drm] capturing error event; look for more information in sysctl hw.dri.0.info.i915_error_state
error: [drm:pid0:i915_reset] *ERROR* Failed to reset chip.

Could you post the output of sysctl hw.dri.0.info.i915_error_state after it failed?
 
Try adding
Code: 
drm.i915.semaphores="1"
to /boot/loader.conf. Since upgrading to 10.2 this annoyance has bothered me more than once. I can almost reproduce it reliably by opening any streaming content in VLC media player and then closing it. If you leave KsystemLog running and use a screensaver that usually does it as well. Since adding this my computer is rock solid. This has been a very recent change and is still being tested by myself but so far so good.

Thank you much for the suggestion. Currently my machine and I are in different continents but I'll try it out as soon as I'm back.
