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
Plasma 6.8.1 update: fullscreen games choppy (fine in windowed), desktop animations laggy - fixed by downgrading to 6.8.0
Choppy frame pacing in CS2 and Deadlock (300–500 FPS) after 2026-10-22 update (linux 7.3.0, linux-firmware-amdgpu 20261019, Plasma 6.8.1) – RX 6600 XT, Wayland – fixed by snapshot rollback
Steam games broken after updating from kernel 7.2.11-1 -> 7.3.0-2 (not fixed by 7.3.0-3)
linux-cachyos 7.3.0-4: amdgpu “Fence fallback timer expired” causes game crashes (RX 6600 XT) (Monster Hunter Wilds)
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)
Cannot login after the latest update from kernel 7.2.10-1 -> 7.3.0-2 (presented with a frozen screen)
Nvidia-open 615.78.08: dGPU runtime D3 “Not supported” on linux-cachyos 7.3.0-4, works on LTS 6.18.55-2
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
Plasma 6.8.1: immediate screen tearing / flickering shadows / black areas on GTX 1650 Ti (HP Pavilion Gaming 15-dk1xxx) - 6.8.0 is fine
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
Kernal 7.3.0-3 - AMD / NVIDEA
Should i stay at linux-cachyos 7.2.11-1?
After update audio is is wery crapy and not loud

Severe display artifacts and flickering on NVIDIA HDMI output after today’s first upgrade (2026/10/22)
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)
After update lost fps
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?

You don’t NEED to update right away. Esp if it may affect your use. I go days, sometimes weeks before updating CachyOS.

Do you use amdgpu? Because of you didn’t specifically install and activate it, you’re likely running mesa, which is the better choice in most cases.

You can safely update, it was fixed the same day and CachyOS is already at 7.3.1.

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.

I’ve updated and havent had issues (yet). Been playing deadlock just fine.

I have three machines with AMD dGPUs, all have been fine with the latest kernel. Worst case scenario, you can downgrade just the kernel and get the rest of the updates (including the certificates).

I always check if my Hardware or parts of it are affected. So it may help to take that into account or to share it as part of your question. Also have you only one kernel installed, for such cases it can be beneficiary to have a second kernel ( I use the lts one for this reason) installed and only ever install one at a time.
