** Description changed: When I resume from suspend, my system initially appears to be frozen. The screen is black and/or the input devices are not working. After several minutes, I can switch to a console (and then to the desktop) but the system is under full load, to the point that even trivial commands will take up to three minutes to execute. The only way out of this situation is to do a reboot. I see that dmesg is showing an NVME related stack trace and then the repeating message "timeout, completion polled". I ran into the same issue a few months ago when I started using my current motherboard (ASUS Prime x470-PRO). It got solved by flashing my BIOS to the latest version. ASUS have not put out any newer since then so I guess this will require a kernel fix. release: ubuntu 20.04 kernel: Linux Dapple 5.4.0-33-generic #37-Ubuntu SMP Thu May 21 12:53:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux + also tried kernel: Linux Dapple 5.4.0-34-generic #38-Ubuntu SMP Mon May 25 15:46:55 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux (developer repository) + ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-33-generic 5.4.0-33.37 ProcVersionSignature: Ubuntu 5.4.0-33.37-generic 5.4.34 Uname: Linux 5.4.0-33-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.11-0ubuntu27.2 Architecture: amd64 AudioDevicesInUse: - USER PID ACCESS COMMAND - /dev/snd/controlC0: jurgen 1998 F.... pulseaudio + USER PID ACCESS COMMAND + /dev/snd/controlC0: jurgen 1998 F.... pulseaudio CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Mon Jun 8 04:43:36 2020 InstallationDate: Installed on 2020-04-05 (63 days ago) InstallationMedia: Ubuntu 20.04 LTS "Focal Fossa" - Beta amd64 (20200402) IwConfig: - lo no wireless extensions. - - enp10s0 no wireless extensions. + lo no wireless extensions. + + enp10s0 no wireless extensions.
