I'm at a loss tbh with ideas. We successfully disable both pipes, then enable pipe A and it all works. Then we enable pipe B and _both_ pipes underrun immediately afterwards. Really strange. Can you please reproduce the issue again on drm-intel-nightly (latest -nightly should also have the display corruptions fixed, so good to retest anyway) and attach a new dmesg with drm.debug=0xe. Meanwhile I'll try to come up with new theories and ideas.
