Hi,

I want to report, that your delivered kernel has problem with STR on my Laptop.
When I run `echo mem | sudo tee /sys/power/state` the systems trys to go in standby mode. Everything shuts down, but the power led flashes fast (how it does every time between going into standby and before the standby is reached). It never reaches the state that the led starts slowly "breathing in and out".

I already tested with the mainline kernel from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15/

And there standby works flawless.
