Scott Brown writes via Kernel.org Bugzilla: I see. The two cards I have tested with are a 64GB ADATA MicroSDXC rated USH-1 Class 10 bought in 2014 and a 32GB ADATA MicroSDXC rated UHS-1 Class 10 V10 A1 bought in 2018, each in a micro-to-full SD adapter. I will see if I can scare up some other cards to test with.
