Hi, seems i forgot to update previously. I've found a workaround if setting "nolapic" on kernel commandline, which puts the machine into 1 core mode, but makes it at least a bit useable. with 5.10.0-8 it can wake up from suspend, but button doesn't work, so i had to systemctl suspend. now with 5.10.0-9 i can both suspend by button and wake up. still not working without nolapic.
