Hi Borislav, thanks for the logs, those were indeed quite helpful.
Attached are two patches, the first one tries to solve the problem by increasing the accuracy of the parameters if we don't match exactly and the second improves the logging of the calculation process by dumping a bunch of intermediate values used. Please apply both on top of my drm-fixes-3.15-wip branch you are already using, if the first one doesn't solve the problem then please provide new dmesg logs with drm.debug=0xE. Thanks in advance, Christian.
