Hi Clint, we tried with 5.1.0-rc3, and could reproduce this issue. Maybe this
is related with specific display(ViewSonic TD2230)?
When the issue is reproduced, we could get the following log:
[ 5657.209872] [drm:pipe_config_err [i915]] mismatch in dp_m_n (expected tu 64
gmch 5190451/8388608 link 288358/524288, or tu 0 gmch 0/0 link 0/0, found tu
64, gmch 4325376/8388608 link 120149/262144)
[ 5657.209898] [drm:pipe_config_err [i915]] mismatch in
base.adjusted_mode.crtc_clock (expected 148500, found 74250)
[ 5657.209920] [drm:pipe_config_err [i915]] mismatch in port_clock (expected
