Tobias Lipper made on the downstream Fedora bugs these comments which shouldn't be lost IMHO in the mist of time:
I found a patch in the upstream kernel that fixes the termal reading for amd juniper cards. This could be the source of the error.
I am not so familiar with kernel development, but I will try the patch and see if it fixes the problem.

----------------------------
I could apply the patch and the module compiles fine, but I found that
su -c 'echo low > /sys/class/drm/card0/device/power_profile'
fixes the problem even without the patch. (at least it turns down the fan to regular)
