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

Server =$repo/$arch
SigLevel = Optional TrustAll

FYI, With the current kernelrelease I have a problem with my SIENNA (6800 series) GPU. The idle usage is through the roof, for some reason the GPU is not clocking back. There seems to be something using it but I have no idea what. This is at the kernel level.

I have succesfully removed the problem on my linux-slim kernel by reverting the "doorbell" commits which seems to cause this high usage bug (in some way I do not understand)

I have searched around alot EVERYWHERE the last few days, and it seems to me I am the ONLY one with this problem (or a sienna gpu?), if there is a need for the fix on this kernel, let me know and I will make it so.

Concerning the previously applied suspend patch;

applying git patch ../suspend.patch
error: patch failed: drivers/usb/host/xhci-pci.c:59
error: drivers/usb/host/xhci-pci.c: patch does not apply
error: patch failed: drivers/usb/host/xhci.h:1892
error: drivers/usb/host/xhci.h: patch does not apply

These patches are no longer actual. I will not forceimplement them on a "fire for effect" basis, that will cause trouble. If there are new, up to date/correct patches available I will implement them.

I don't have time to codereview right now -- might be they got merged aswel.

Hey gofree thx for the heads up.

I implemented the 8 patches and everything seems ok. I do not have any znver2 based laptop in my possesion though, so I idea if it works or what the outcome is.

Thanks again!

Do you think you could include 8 patches from here

specifically link for patches

@eggz Well I am currently on 11.16 and once I install 12.02 I cannot do anything except hard reset once I give reboot command. How to do this ? Can you find me on Discord ? TechXero ~ DarkXero#5199

I See. How strange, I have a 3900x right here so it shouldn't be that diffrent from your CPU, and rebooting works just fine, so I really don't know what to tell you. :-(

Your older kernel will work for many years to come, but I suspect by then you will have found what the real problem is...

I have looked upstream for you and there is no mention of a reboot issue with the latest kernel..

Can you give your journalctl output right before your computer freezes?

Before restoring my system was rebooting fine. Now after formatting it and installing Arch fresh.

Rebooting not booting, meaning, when I type sudo reboot or reboot, or even select reboot from panel it goes through motions then freezes on black screen that has the 2 Kernel lines top left..

Keyboard is unresponsive I have to hard reset.. 5.11.16-amd-znver2 works great.. If I update same issue.. What could I be missing if older version works not new one ? If I was missing anything then even older version shouldn't work right ?

@techxero, so you did an arch fresh install, but it was working fine before upgrading the kernel? This sounds a bit confusing to me, when did you upgrade? before or after the fresh install?

I have this kernel running on a bunch of systems, all of them are working fine. I also haven't got any complaint yet for this kernel. I'll never say never, but for now all evidence points towards your install missing having another problem instead of the kernel having a problem.

At what point exactly do you have a black screen? After grub? After the rootswitch? What do you see on your screen after grub? If I had to take a wild guess guess with almost no info (low hitrate though), it seems like your created ramdisk image is completely failing you.

@eggz Thanks for this but recently had to do fresh install of Arch now when using this Kernel and I try rebooting it just hangs on black screen. I am on Ryzen 5 3600X so a ZEN2 CPU.. Was working fine before upgrading to 5.12..

Seems 5.12 isn't yet ready for release. 5.11.16 is last one that works. So am sticking to that setting update to ignore for now :(

Tried Repo and compiling same result :(

Yep, touchpad is working again with the latest changes. Thanks for your quick response! Interesting how the config is split.
