My system will take about a minute to resume from suspend, during which it is unresponsive to input. I get a blank screen (no backlight) until the login screen is displayed, at which point everything functions as normal. The keyboard backlight key does work in this state (expected), but the caps lock indicator LED does not toggle on until the login screen is displayed.

Here are the journalctl logs from kernel, systemd-logind and systemd-sleep during the process of suspending and resuming the system immediately:

Things I have tried

• Installing latest updates through Software Updater and sudo apt update && sudo apt upgrade


• Adding amd_iommu=off to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, followed by sudo update-grub


• Various other GRUB_CMDLINE_LINUX_DEFAULT tweaks

Any idea what the problem might be? I've read in a few places [1] [2] that Ryzen 5000 series CPUs have problems with sleep on Linux. I feel like the next logical step might be to upgrade/downgrade to a different kernel version, but I'm not sure what I should be looking for when picking a specific version, rather than aimlessly guessing which to install (perhaps changelog keywords such as "AMD" and "ACPI"?).

Any help would be much appreciated. :)
