You have been subscribed to a public bug: I have installed Ubuntu 24.04 on my Lenovo ThinkPad T14 Gen 3 (AMD Ryzen™ 7 PRO 6850U with Radeon™ Graphics × 16). Type - 21CF-003QAU
Since installation, the following problem has occurred: - Whenever I suspend the system (e.g. power off menu > suspend), the system successfully goes into a suspended state. - When I wake the computer, the computer wakes and presents me with the login screen - I can log into the system, and the mouse and all previously open windows appear to be working, sound is working etc - I CAN'T seem to open any new applications or run any new commands at this time (no error messages, just nothing starting) - Approximately 30 seconds to 1 minute later, the system freezes completely. No error messages, and I can see everything on the screen. But mouse/keyboard input stops, sound stops, and I have to physically hard restart the laptop. - Example is caplock key light on keyboard stops responding. Interestingly the Esc/FnLock key light still works I have updated all the firmware / BIOS to the latest versions, and the issue still persists. I have run Ubuntu from a Live USB on the same machine, and when suspending, all appears to work OK. I have done a completely fresh install with default installation parameters, and system freeze as explained above occurs every time.
