Has anybody else seen anything of the following drm error? I had 414 
copies of
it in my most recent dmesg:

error: [drm:pid9:i915_gem_object_unbind] *ERROR* Attempting to unbind 
pinned buffer

   And have been getting it for some 4-6 months now after an update. I'm 
not real sure when it started,  just an approximate time when I noticed it.
I am currently running:

FreeBSD pcbsd-1011 10.2-RELEASE-p15 FreeBSD 10.2-RELEASE-p15 #0: Thu Mar 
17 11:41:37 UTC 2016
   root@amd64-builder.pcbsd.org:/usr/obj/usr/src/sys/GENERIC  amd64
        FreeBSD ver:.......10.2-RELEASE-p15
        PC-BSD ver:........10.2

On an ASUS MB using an intel video gpu on the motherboard.
   Sorry, I dont know what other info might be germaine but would be 
very quick  to supply
   same as advised.

In a way of troubleshooting I shut the system down and turned power 
completly off
  for several  minutes to allowthe power supply to completly bleed off.
  This because dmesg seems to pick up erroprs generated and repoerted in 
previous dmesg lists
  After power-up,  the following is  the relavant part opf the dmesg errors:
---
  info: [drm] Initialized drm 1.1.0 20060810

error: [drm:pid2006:gen6_sanitize_pm] *ERROR* Power management 
discrepancy: GEN6_RP_INTERRUPT_LIMIT
---

after a short while (~10 minutes) ,  no further drm errors were reportd


More important, has anybody seen a cure for it?

The world would be a nicer place if everyone took a chill pill.
It would be even nicer if some of them choked on it.
