Created attachment 296201 [details] dmesg output I have a HP laptop with AMD ryzen 5800u APU. I can't suspend the laptop. When I try to suspend, after screen turn off, the fan run crazy then it just turn off. I have to boot from beginning.

try compile latest kernel 5.12.y with some patches (see 1)) 1) https://gitlab.freedesktop.org/drm/amd/-/issues/1230 2) https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable-rc.git/log/?h=linux-5.12.y
There are a lot of patches that are needed for this, everything identified thus far is targeted toward 5.14. A community member has a kernel with all of them backported to 5.13 if you would like to try sooner. https://gitlab.com/belegdol/kernel-ark/-/commits/fedora-5.13-renoir-s0ix-backport/
This is sorted in 5.15 and all later kernels, this issue can be closed.
