<pre>For the last good kernel:
[drm:intel_dp_compute_config], DP link computation with max lane count 2 max bw
0a pixel clock 141000KHz
[drm:intel_dp_compute_config], DP link bw 0a lane count 2 clock 270000 bpp 24
[drm:intel_dp_compute_config], DP link bw required 338400 available 432000
For the first bad & the nightly kernel:
[drm:intel_dp_compute_config], DP link computation with max lane count 2 max bw
0a pixel clock 141000KHz
[drm:intel_dp_compute_config], DP link bw 06 lane count 2 clock 162000 bpp 18
[drm:intel_dp_compute_config], DP link bw required 253800 available 259200
Might the problem be related to bpp which changed from 24 to 18?</pre>
