So it happens every suspend-resume. This time disabling wifi doesnt work, no zombie processes
just "hiccups", killing gnome shell doesnt help still getting these "freezes"

So I start to think that something might be wrong around CPU. Yet
temperatures are fine. And it only happens after resume from the S3 ACPI
sleep.

Title:
  After resume from suspend the system got hiccups/freezes on Thinkpad
  T14 AMD gen 4

Status in network-manager-openvpn package in Ubuntu:
  Invalid

Bug description:
  Not sure whether that is always Network Manager
  Seems after return from suspend the systems becomes unresponsive for 1-2s more seconds every 10-15s. One cpu got 100% load and some processes goes zombie.
  NetworkManager main process is using 70-100% of cpu time while nm-auth-openvpn is zombie

  So I am not sure whether it is kernel, networkmanager or cpu problem
