[Fedora 15]error during shutdown

[magina antimage]

HI,
  I have integrated systemd with my SDK
 I am having some problem during shutdown,my hdmi module isnt getting
unloaded properly
i am getting following error:
"backdoor_queue_job:ERROR: Job queue <1> timeout, job = 61"
"backdoor_queue_job:ERROR: Job queue <1> timeout, job = 62"
and so on,
but if i manually remove my hdmi module and give shutdown command it works
fine
Any guess what is causing problem
