Several days ago, I tried to update my CachyOS system. And seen the below warning from Pacman itself
Update notice: Kernel 7.3.0-2 has issues with amdgpu particularly causing black screen on AMD dGPUs
At first, I was like gonna do the update, because I don’t have an AMD CPU/GPU. Then I went to check on the internet and found lots of issues with both Kernel 7.3 and KDE Plasma 6.8.1. Even affecting NVIDIA GPU.
Some of the examples
Linux 7.3 - GPU idle increased from 10 W to 60. Anyone else?
Partial upgrade for ca-certificates-mozilla
Steam games broken after updating from kernel 7.2.11-1 -> 7.3.0-2 (not fixed by 7.3.0-3)
Cachyos kernel upgrade to 7.3.0 - fails on AMD
After latest update to cachyos-rate-mirrors the speeds are horible
GPU and CPU Fans Running at Double Speed under 7.3.1
Cachy kernel version 7.3.1 breaks the dual display (DisplayLink device) (KDE Plasma) (Kwin)
Steam games broken after updating from kernel 7.2.11-1 -> 7.3.0-2 (not fixed by 7.3.0-3)
Is there a reason that the BORE kernel is stale (7.2.10 vs. 7.3.0)?
After Recent Update, Shut Down Takes Over 1 Minute - User Manager Issue?
Behringer UMC404HD - fail with Kernel 7.3.0
LACT power cap write fails with “Operation not supported (os error 95)” on 7.3.0-3-cachyos
Updating to 7.3.0-3-cachyos causes UMC204HD Audio Interface to be unusable
Issue with AdaptiveSync kernel 7.3+
Keyboard Backlight Not Working With 7.3 Kernel
Should i stay at linux-cachyos 7.2.11-1?
After update audio is is wery crapy and not loud
Audio echo in FAudio/Proton games on launch — regression starting linux-cachyos 7.3
Update causing KDE Plasma crash or blackscreen at boot
After KDE 6.8 update, Desktop Animations lag and Games run on 48fps
7.3.0-2 on RX 9070 XT: no black screen, but a DCN401 MCM LUT warning on HDR enable (Plasma 6.8.0)
Not every link I shared is completely relevant to me, but the amount of issues on Kernel 7.3 and KDE Plasma 6.8.1. Even affecting NVIDIA GPU made me hesitant.
Because of this hesitation, I also didn’t update Firefox CA-Certificates security update.
Should I update now?
So here’s temporary fix and one that Arch technically supports but the devs highly recommend against it. But I have used it in the past for a short time when KDE 6 first released and was buggy as hell on my system.
You can blacklist certain packages from updating by editing /etc/pacman.conf
You should see under [Options] IgnorePkg = It might be commented out or if it’s not there at all just add it manually.
So something like IgnorePkg = linux amdgpu
Then save and update like normal. Just don’t forget about it since the longer you leave it the more likely something will break.
