--- Comment #19 from Christian König deathsimple@vodafone.de ---
From the logs you are always getting the same set of paramaters, even when you
change the maximum used in the fix:
[drm:radeon_compute_pll_avivo] 162000 - 161990, pll dividers - fb: 1425.4 ref: 21, post 6
With a maximum of 32 and a post divider of 6 the ref divider shouldn't be more than 5, but it still stays at 21.
Thise means there is something wrong with the way you install the kernel module (or the modification you make). Please double check that you got the right kernel module loaded.
