re-run the install LACT ujust command, AMD asked us to stop enabling overclocking by default in the kernel and a kernel argument is now required then restart

So having the same issue and re running the lact ujust does not fix it for me. How can I append the kernel argument manually my self?

ujust --show install-lact Then grab the karg line

Thinking about it it might not be working for me because I'm using refind intead of grub :Thonk: prob need to add the kernel parameter to refind. (i don't use grub as my pc asrock bios dosn't not work well with it works fine in refind) hmm it still not working I added
amdgpu.ppfeaturemask=0xfff7ffff
amdgpu.ppfeaturemask=0xfff7ffff
to the kernel arguments in refind i got that from running
printf 'amdgpu.ppfeaturemask=0x%x\n' "$(($(cat /sys/module/amdgpu/parameters/ppfeaturemask) | 0x4000))"
printf 'amdgpu.ppfeaturemask=0x%x\n' "$(($(cat /sys/module/amdgpu/parameters/ppfeaturemask) | 0x4000))"
which was in the ujust lact command and also in the archwiki apperently its for caculating the best feature bits for your gpu this is my /boot/refind_linux.conf
"Boot with standard options" "rhgb quiet root=UUID=93b6a167-14d5-4456-a23e-8b1bef24f1ca rootflags=subvol=root rw ostree=/ostree/boot.0/default/2c3aef980e880a5a22661003a7011d1d3f7aa4e30694643cccc471d237b7814b/0 bluetooth.disable_ertm=1 amdgpu.ppfeaturemask=0xfff7ffff sysrq_always_enabled=1"

Fixed it by having refind boot grub instead of booting bazzite directly. Kinda redudent but probably better anyway so that I can have the snapshots in grub.
