dmesg output with initcall_debug, no_console_suspend, ignore_loglevel

This bug started recently on kernel 5.17.x I believe, I should do a downgrade to confirm this, however I'm pretty confident this issue wasn't here before a recent upgrade I've made to the kernel.

So far testing under the Linux lts 5.15.32-arch1-1 shows that this issue is not present.

The hardware is a ThinkPad T495 AMD Ryzen 7 PRO 3700U with a Radeon Vega RX10.

Current linux-firmware installed : 20220209.6342082-1

If an X11 server is running resuming fails as the screen never comes back on, weirdly in the TTY it does resume, not sure if it's a relevant detail.

Dmesg attached was made with cmdline options : initcall_debug, no_console_suspend, ignore_loglevel for lots of outputs.

Here is some relevant logs :
