Thanks. The second option seems the least intrusive. Also, I intend to "downgrade" the kernel from "Kernel:stable:Backports" to the 15.5 patched kernel that Takashi Iwai provided; I know it works with WiFi, and it probably also works with hibernation. If that is so, it should be the least problematic route. I have a brand new laptop (lenovo L14 Gen 3 AMD), and I use the "ancient" Leap 15.4... it is bound to cause problems. I suppose we can close this Bugzilla. Thanks a lot for the quick response.
