Hello,
If you have 40xx series Nvidia in your laptop and suspend/resume issues, definitely try bluefin-nvidia-dx-open (OSS kernel modules) with parameter: nvidia.NVreg_EnableS0ixPowerManagement=0.
This has finally gotten my Nvidia 4060 to work super-stable after nearly a year of tinkering with various options. I have had my laptop suspend/resume since last Sunday close to 65 times with zero issues and an uptime of 6 days at this point.
This is the first time in a year (since I got this laptop) where I’ve been able to go with Nvidia enabled for the entire week!
Finally rock-solid!
