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.
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.
