Yeah, looks like power saving states indeed. If you edit /etc/default/grub and add "nvme_core.default_ps_max_latency_us=0 pcie_aspm=off pcie_port_pm=off" after "quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT=, save, then run "sudo update-grub" and reboot, and leave it overnight, does the problem go away?
