Looking at your first post, its not network related. Note those previous settings do not persist. Running out of ideas. As PCW mentioned ensure the NIC interrupt is pinned to isolated core 5

You mentioned graphics so you probably have an Intel i915 GPU which hangs on my PC. Add these to grub to lock it downi915.enable_dc=0 i915.enable_fbc=0 i915.enable_psr=0
