@atirutw and @Thermionix, you might want to look at NVIDIA/open-gpu-kernel-modules#1142.

Setting NVreg_UseKernelSuspendNotifiers=0 and NVreg_PreserveVideoMemoryAllocations=1 in the kernel parameters as recommended in NVIDIA/open-gpu-kernel-modules#1142 (comment) fixed the issue on my laptop:

The issue seems to be related to SELinux and I guess we can only wait for newer drivers to manage the issue in a better way.

Note that I have SecureBoot (and full disk encryption) enabled on my system, so hibernation is not possible (hence the suspend-then-hibernate and hibernate services are disabled).

nil change, interestingly NVreg_UseKernelSuspendNotifiers=0 won't change the loaded value for me
