ERROR: kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun
When booting Linux on the new kernels (5.14 and 5.15) I have no image, just a black screen with occasional messed up colourful lines. Everything works perfect on Linux 5.13.
I have Integrated Intel HD Graphics 630 + Discrete Radeon RX Vega M GL Graphics. My laptop info.
