Chances are this is fixed via:
commit b449a43f56d412a0260f3df08b061a5e937db77b
Author: Martin Peres <martin.peres>
Date:   Mon Sep 9 00:43:27 2013 +0200

    drm/nouveau/therm: ack any pending IRQ at init
    
    This is safe because ptherm hasn't been configured yet and will be a
    little further down the initialization path. Ptherm should be safe
    regarding to runtime reconfiguration.
    
    v2:
      - do not limit this patch to nv84-a3 and make it nv84+
    
    v3:
      - move the ack to fini()
      - disable IRQs on fini()
      - silently ignore un-requested IRQs

This will make it in 3.13 only

Comment 2 Michele Baldessari 2013-12-25 18:28:29 UTC
Could you try 3.13-rc5 http://koji.fedoraproject.org/koji/buildinfo?buildID=486630 and let us know if this specific issue is gone or not?

Thanks,
Michele

Thank you Michele!

Yes it seems the error disappeared, but I've tried on Fedora 20

Kernel - Linux version 3.13.0-0.rc5.git0.1.fc21.x86_64 (mockbuild@bkernel02) (gcc version 4.8.2 20131212 (Red Hat 4.8.2-7) (GCC) ) #1 SMP Mon Dec 23 14:23:13 UTC 2013

"dmesg |grep unhandled" - all clean!

Comment 4 Ben Skeggs 2014-01-07 00:04:57 UTC
Thanks for reporting it's fixed.  Will close :)
