ohci: WARNING: addr ... not found

Hi!

Since upgrading from 5.1 to 6.0.1, I get a lot of new warnings I
hadn't seen before:

Mar  2 10:23:33 nas /netbsd: ohci1: WARNING: addr 0x00001b80 not found

Mar  2 11:23:47 nas /netbsd: ohci2: WARNING: addr 0x00001b80 not found

Any ideas what this means and why it's appearing now?
