Arch Linux User Repository

something weird with this kernel: when I try to poweroff by doing "poweroff" or "systemctl poweroff" with this kernel, it always winds up rebooting. I thought I was going crazy until I reinstalled the standard linux-5.11.arch2-1 kernel where it then behaves normally. how do I even begin to debug this ?

I was trying to figure out other issues where I'm getting the following error mesgs:

amdgpu: Unsupported power profile mode 0 on RENOIR

This is on a HP Envy x360 with the 4700u.

I identified the AMDgpu troubles in the linux-next tree and "backported" the patch

https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?id=85f4f00c1e88b2a5aced59cca7354631e8889dfb

Description:

This reverts commit 8866a67ab86cc0812e65c04f1ef02bcc41e24d68.

This breaks hotplug of HDMI on some systems, resulting in
a blank screen also causes failures for displays to light up
on other systems.

There are a bunch of other fixes in upstream (linux-next), but this one seems standalone and is compatible with the stable tree. I'm not going to put everything upstream inhere, this seems to be enough for me to supress all the AMDGPU errors.

I tested this on 2 machines already and it seems to have good results.

Nice man! Lemme know the results.

Just to be overly clear, set those options to

# CONFIG_AMD_SFH_HID is not set
# CONFIG_AMD_PMC is not set

Let me know that it fixes anything if you are able to. Good luck!

@eggz

Thanks. I don't mind compiling as it was my main excuse in buying so many darn cores in the first place :)

@dedguy21

There were alot of renoir code additions in 5.11 (and I activated them), and I can only hope they were good. If they aren't, theres not much I can do about that. I don't even have renoir hardware :/

I also saw some AMDGPU problems on my vega based hardware on 5.11, but if your problems are CPUrelated, that sends even more chills up my spine ...

I hope they will fix it in 5.11.1 or later. I think it's best you keep checking on every release if things get better or not.

Another option is to disable the new RENOIR options and recompile the kernel:

CONFIG_AMD_SFH_HID=m
CONFIG_AMD_PMC=m

I think PMC is a strong contender in being a problematic new module explaining the troubles you have..

IF you're intrested in this last option but don't like to compile, I'll do it for you, just let me know. (since I don't have the hardware..)

I have a Dell G5 SE 5505, ryzen 4900H renoir chip, plus radeon 5600M graphics. Any rate have been using this kernel since you split it away from linux-amd, and everything was working fine until this last 5.11-xx update. Performance was horrible, machine stuttered at everything, even booting took longer than usual.

Just an FYI, not sure if anyone else will have the issue, but I had to downgrade back to 5.10-16, that fixed my issues.

Your vbox modules are not ready for linux 5.11 . You will probably have to wait for an update for that module.

Also why is everyone using virtualbox for virtualisation on linux? Just use libvirtd/Qemu kvm ...? You know like ... with present in-tree kernel modules?

It fails with my dkms modules:

@eggz Yes its my first custom kernel install, all I did was install the aur package then restarted. Right now I saw that I have some updates to do and linux-amd-znver2 5.10.v.13-1 is also updating. I'll try the grub config after, thank you!

ehm.. did you run grub-mkconfig -o /boot/grub/grub.cfg ? and then pick the new kernel? Is this your first custom kernel install or not?
