Arch Linux User Repository

GCC13.1 is mainlined in arch, so this means znver4 support can kick off on this kernel. The graysky compile patches have been updated too.

This kernel now natively supports the znver4 arch, but this kernel will most likely keep working on all AMD ryzen hardware. It's better to be able to address certain small perks or issues per architecture now and in the future.

If you use znver3 based hardware, please use linux-amd-znver3
If you use znver2 based hardware, please use linux-amd-znver2
If you use raven based hardware, please use linux-amd-raven

Tired of compiling? Use this binary repo instead! Add this at the end of /etc/pacman.conf :

Hello, seems amdgpu hasnt really tested their code yet again before releasing. If you have issues, downgrade and please tell me your system.

@anarconda Unfortunatly i dont see any logs that concern your amdgpu problems :)

With 'local/linux-amd 5.16.v.0-2' I'm not getting X system and the screen shows messages about "pstore: crypto_comp-decompress failed, ret 0 -22!" and "Bluetooth: hci0: Failed to read codec capabilities (-56)".

Thanks for your efforts. Regards.

Hi all, thanks for your comments and for looking into it. After switching to linux-amd I soon experienced 2 crashes, but did not find it worth mentionining yet. Seeing @deemon had the same experience I decided to add my experience.

I've been trying to get a kdump kernel working to provide something more than "it crashed", but with no succes yet. However, I haven't experienced another crash since then either.

I think in the meantime the package was however updated from linux 5.15.11 to 5.15.12, so the kernel I'm running is not identical.

That's all I have unfortunately.

No crashes with AMD Ryzen 5 5600X 6-Core.

Here instead no crashes with Ryzen 5800X

I attempted to fix the problem by aligning the config to the vanilla (archlinux kernel) config as best as I could. As I dont have zen3 hardware or any detailed logs, this is the best I can attempt so far ..

That's interesting, also, no idea why :-D. Ill keep searching.

@deemon just wanted to share I'm experiencing the same issue. I've reverted to the default Arch kernel, on which I don't experience crashes.

I'm running native Arch Linux on AMD Ryzen:

root@arch:~ # lshw -C CPU -short
H/W path            Device          Class          Description
==============================================================
/0/4                                processor      AMD Ryzen 7 5800H with Radeon Graphics


root@arch:~ # lsb_release -a
LSB Version:    1.4
Distributor ID: Arch
Description:    Arch Linux
Release:    rolling
Codename:   n/a

don't know why, but this kernel has crashed me like 3 times already in last week. whereas "normal" manjaro kernel has not crashed for months. have 5950X.

You can read all about it here:

All kernels do it, were just being verbose about it. Just keep calm and boot :-)
