Hello, I can confirm this is a kernel bug which manifests on the Lenovo IdeaPad 3 15IIL05.

Attached is a tarball from the Fedora "Problem Reporting" tool which includes the dmesg and other system data. I realize this isn't a Fedora bug tracker but this is a kernel bug and there doesn't seem to be any other discussion about it.

Below is the relevant log telling us no handlers are registered for the hardware:
