--- Comment #13 from James Ettle (james@ettle.org.uk) --- Also seen here under kernel 5.9.12 with a Ryzen 3400G and a Samsung LU32H850UM on DisplayPort:
[drm] enabling link 1 failed: 15
This is somewhat intermittent, and it comes back after power-cycling the monitor (which is configured with manual input selection).
Not seen with Dell or Lenovo monitors on same port.
I'll try a different DisplayPort cable just to check...
