Title: HWE-22.04 Kernel 5.19 breaks suspend/wake on newer AMD Ryzen CPUs Status in linux-hwe-5.19 package in Ubuntu: Confirmed Bug description: After 22.04 LTS upgraded the linux-generic-hwe kernel to 5.19.0.32 (from 5.15.0.60) suspend/wake up is broken on my laptop. The system refuses to wake up in about 50% of the cases, seemingly random. The only "solution" is a forced system power down. Reverting back to 5.15.0.60 resolves this issue immediately. I suspect some patch was not re-applied to 5.19, since there are many postings on Reddit (for instance) about sleep problems with newer AMD CPUs, but 5.15 was running beautifully. My machine is a Lenovo Thinkpad T14s AMD Gen 3, AMD 6850u CPU. UPDATE: See attached log. This may not be a case of the laptop failing to resume, but a case of the laptop not suspending properly! What happened was the following. When packing in my things, I closed the laptop and put it in my bag. At home I picked it up again, and immediately noticed how unusually hot it was. The laptop didn't resume properly on opening the lid, but was frozen as before. So this might actually be a case of the laptop FAILING TO SUSPEND properly, instead of failing to wake up. UPDATE: I just noticed the battery was down to the low 40% from at least 80%. Given the temperature on opening the laption I suspect the CPU has been working hard during "sleep time". EDIT: Changed title after confirmation for earlier Ryzen 5000 CPU.
