Using a Lenovo 15ADA05 laptop, whenever I resume from suspend I see this
warning on console:

I switched to the Kernel:stable:Backports image and also upgraded the bios to
the latest version, without apparent change. Before Leap 15.4 I used Fedora 35
for a few months and I don't recall ever seeing this.
