--- Comment #25 from Dan Merillat bugzilla@dan.merillat.org --- Unfortunately, I had to set this down to 32 to work on my system.
Radeon HD 3200 (onboard, RS780) Monitor Viewsonic G225f Kernel 3.16-rc3

CRTs are getting increasingly rare - perhaps a tunable for this so us fogies with 100 pound monitors can set it where it works on our system? For me, it's a trivial patch to carry forward but setting something like drm.ref_div_tweak=32 in my grub config would be easier.
I haven't been able to use a kernel since commit 3216701 drm/radeon: rework finding display PLL numbers v2.
