Since upgrading to Ubuntu 26.04 (kernel 7.0.0-38), waking from s2idle by opening the lid, pressing keys, or pressing the power button takes about 75 seconds. Waking by RTC alarm (amd-s2idle test) is instant. The problem did not exist before the upgrade. BIOS updated from 304 to 308, no change.
Hardware: ASUS Zenbook 14 UM3406HA, AMD Ryzen 7 8840HS. amd-s2idle report attached. ** Attachment added: "amd-s2idle-report-2026-10-13.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2171271/+attachment/6009957/+files/amd-s2idle-report-2026-10-13.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2171271 Title: Slow resume (~75s) from lid/keyboard on ASUS UM3406HA after upgrade to 26.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2171271/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
