Public bug reported: I have a Lenovo ThinkPad T14 Gen 3. I got it last fall and installed Ubuntu 23.10 the day after 23.10 was released. After a couple weeks of issues while 23.10 stabilized, it worked pretty much fine.
Sometime in April of this year, my device/OS combo which had been working suddenly developed a problem. Suddenly I began seeing a problem where when I closed the lid to sleep the machine, waited a while, and then opened the screen again, the screen would be black and the unit would be totally nonresponsive. When the device is in this state, the red LED on the back in the "THINK" logo stays at a fixed value rather than pulsating as it normally does during sleep, and the lights on the FKEYs (for example normally I can tap F1 which will mute/unmute the speakers or F4 which will mute/unmute the mic, and both these actions will toggle a light on that key) are nonresponsive. The only way to exit this state is to hold the power button until the unit turns off, then press the power button again to rewake. (The fact the FKEY lights do not respond makes me believe the device has actually crashed at this point and it isn't just a stuck-off screen.) For a couple months after this I saw the problem between every other day and twice a day. Last week I upgraded to 24.04 to see if this would help with the problem. It has not resolved the problem. Since the upgrade I have seen the problem twice. I gathered the attached logs immediately after waking following one of these lockups/hard power cycles. This has been a huge inconvenience so I will happily gather any other logs needed. Two other pieces of information, not sure if helpful: 1. *Once*, exactly once in April, when I saw this problem, upon opening the screen the screen lit up and displayed three lines of a text error. The words "amd ring 0 error" were visible. The screen then went black (and stayed black) before I could record the other text. 2. The "Firmware Updater" app currently says my "System Firmware" can be upgraded from 0.1.46 to 0.1.52. I didn't see that until this week. I am going to try installing this firmware update and I will report back here if it does/doesn't make a difference.
