I don't know if this is related but it fixed my problem with wake up from suspend. This is on a desktop with an Asus Rog Strix B450-F Gaming motherboard and Focal Fossa.
I have changed these settings in BIOS - Used DOCP settings on the memory - USB power delivery in SoftOff is set to Disable - PSS support is set to enable - Serial Port is set to OFF In AMD CBS - IOMMU is set to Disabled - Global C-state control is set to enable - Power Supply Idle Control is set to Low Current Idle I think the most important setting is to disable IOMMU. Instead I have added "iommu=soft" in GRUB_CMDLINE_LINUX="" in /etc/default/grub -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848771 Title: Reboot after resume from suspend (deep) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-upgrader/+bug/1848771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
