Public bug reported:
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.
