https://bugzilla.kernel.org/show_bug.cgi?id=206349 Jimmy Berry (jimmy@xxxxxxxxxxxxxxx) changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jimmy@xxxxxxxxxxxxxxx --- Comment #1 from Jimmy Berry (jimmy@xxxxxxxxxxxxxxx) --- Looks like I have the same thing on 5.14.6 with a Radeon 6900 XT. >From 5.13.8 I was able to run 4 x 4k @ 60hz + 2 x 4k @30hz. Hardware should support all 6 at 60hz, but that is all I can get to work. As of the update to 5.14.6 I can now only run 3 x 4k @ 60hz + 3 x 4k @ 30hz. Wondering if this error is related. I can supply more detail.
