    Question Suspend bug in kernel 5.8.0-43-generic

    For the past few days, I've been dealing with suspend issues happening in my Ubuntu OS 20.04. Due to some reasons, resuming after suspend does not work sometimes. I've checked kernel logs and noticed following log message

    x86/pm: family 0x16 cpu detected, MSR saving is needed during suspending
    I previously thought that recent kernel update could be a root cause but after downgrading to previous kernels nothing changed. Does anyone has an idea what could be a reason for this?

    So it used to work? Perhaps Nvidia drivers were upgraded as well and caused the issue?
