Public bug reported: ThinkPad Z13 running Ubuntu 24.04 with all updates.
I can reliably make the system hard reboot then become unbootable until hard reset with the power button. Steps to reproduce ------------------ 1. Boot using 6.8.0-35-generic stock kernel from the repo 2. Login to the desktop 3. Top right GNOME menu, power button, suspend 4. Wait for the system to suspend 5. Wake the system up 6a. Unlock to the desktop or 6b. Wait Expected outcome ---------------- System functions as if nothing had happened Actual outcome -------------- Screen goes black, system 'restarts' (in quotes because it's unusable) and begins looping. I see the Lenovo logo, black screen, reboot, then back to the Lenovo logo. I never get a usable desktop again. Workaround ---------- Booting the 'Mainline' 'PPA' kernel linux-image-6.9.3-060903-generic does not exhibit this behaviour. My spidey sense points to the AMD GPU driver. But this is wild speculation.
