Hi Christian. Thanks for your help. They are not 100% the same. I hope that I am not misleading you. My, aplogies in advance, if it works out to be so.
No problem at all. It's still quite likely that my patch is the source of the problem.
xorg3.15, Kernel 3.13.7 vs. 3.14
We should just make sure that it is indeed the only change in the system and we don't have an issue like two patches affecting each other or something like that.
Beeing based on kernel 3.13.7 vs. 3.14 for the two versions sounds like we should make that sure first.
Tonight I will make a new build environment to test PURELY the patch/un-patch. I am a bit new to building kernel Dri/Drm modules. But I should be able to figure it out.
Let me know if you need any help.
It might be that my LCD does not like 23.98? Thanks. I will post back with the results.
Might be, but I would rather guess that the PLL isn't stable enough any more with my changes.
When the values get higher you usually get better matching results, but the electrical signal also gets more unstable. Your LCD is probably just a bit picky what signal it gets as input.
I've attached a patch that artifically limits the dividers and so might produce better results. Please try it and report back if that changes anything.
