Dell XPS 9575 has black screen during boot after update to Linux kernel 5.14

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.

have you tried changing the graphics settings to use the Discrete one?

Linux doesn’t boot with kernel 5.14, shows caleidoscope of colourful lines instead. Boots normally with 5.12.

journalctl ERROR: _____ kernel: i915 0000:00:02.0: [drm] *ERROR* CPU pipe A FIFO underrun

Please, help! Main topic created here.

Please read this:

Especially the Linux has multiple kernels section, then try an LTS kernel and hopefully the problem will go away “automagically”. :grin:


Well, if this problem isn’t fixed timely then it means I wouldn’t be able to use the next LTS kernel, right? So I think it’s better to report the problem somewhere to have it fixed before the new LTS is released.

BTW, I found several other guys that had the same problem: FS#72134 : linux 5.14.* gpu bug with i915 DRM

Did you read the guide??? LTS = Ultra-stable, which means whenever a new LTS kernel comes out, don’t install the nn.0 but do install the nn.01:stuck_out_tongue_winking_eye:

Again: did you read the guide?

  • install 5.10 AND 5.4 and see which troubles you the least and then you’re on the LTS bandwagon…
