Looks like a drrs vs. readout fail.

Comment 7 Lakshmi 2019-04-05 05:56:17 UTC
Assuming this is a regression, priority is set to highest.
There is a similar bug report from community Bug 110308.
Comment 8 Jani Saarinen 2019-04-09 11:31:18 UTC
There is fix from Vandita: https://patchwork.freedesktop.org/series/59184/ this now in trybot still.
Comment 9 Jani Saarinen 2019-04-09 11:51:26 UTC
Also Imre's fix needed on ICL-DSI. https://patchwork.freedesktop.org/series/59071/
Comment 10 Martin Peres 2019-04-09 11:54:56 UTC
The bug is ICL-specific, and this feature is a power optimisation. We need to understand if this failure is indicating a possible black screen.

Until it is better understood, the user impact is deemed highest. The fixes should however be landing soon, which would make the exercise useless.

Let's wait for https://patchwork.freedesktop.org/series/59184/'s results to understand better :)

See you tomorrow!
