The machine will successfully go into s2idle suspend (sleep) but upon waking, the system will immediately freeze hard. In its frozen state, the mouse pointer will be visible against a black screen. Here are the troubleshooting steps I have taken so far: - Can successfully reproduce under Ubuntu 20.04.2 (gdm3), Kubuntu 20.04.2 (sddm). For what it's worth, I can also reproduce this under Manjaro (stable), so it's conceivable this is a kernel bug. - There's some evidence online that this issue, or something similar, was introduced in/around kernel 5.6.19 -- I have not been able to get Ubuntu to boot under a kernel earlier than 5.8 so I cannot confirm this. - Updated BIOS to latest (1.6). 'Block sleep' is off. System > SATA is 'AHCI'. Post Behavior > Fastboot is 'Thorough'. Secure Boot is disabled. - Determined that this BIOS does not appear to support 'deep' sleep, only s2idle. - The problem does NOT occur if I boot to an Ubuntu 20.04.2 live USB disk. I compared the drivers that are loaded in that environment vs. those that are loaded under the installed OS and did not notice anything suspicious. I am happy to supply any diagnostics or logs that are requested. --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.17 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: brian 916 F.... pulseaudio CasperMD5CheckResult: skip DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-05-16 (0 days ago) InstallationMedia: Kubuntu 20.04.2.0 LTS "Focal Fossa" - Release amd64 (20210209.1) MachineType: Dell Inc.
