--- Comment #22 from kb at spatium.org --- I've also added this line DRM_DEBUG_KMS("in patched branch: %u\n", ref_div_max); add the end of your patch, i.e. after ref_div_max = min(ref_div_max, pll->reference_freq / in_min); just to make sure the new code gets hit. I see this in dmesg [ 23.002707] [drm:radeon_compute_pll_avivo] in patched branch: 13 and I'm attaching the full output as well. Hope it gives you some more ideas. -- You are receiving this mail because: You are watching the assignee of the bug.
