I found some mention of that in some other linux mailing
lists. Apparently it means nothing, and the way to get rid
of it is to wait till a new kernel shows up that has the
corrected code which doesn't spew spurious warnings.

I've not tried F8, but I've seen it on 7 & 9. For some reason, at
*that* time, the system wasn't able to figure out what to do with some
device plugged into a USB port. But it does work out what to do later
on, when you actually do want to make use of your mouse or keyboard.
Perhaps it doesn't wait long enough, after detecting a device, before
complaining about it.

I noticed that 9 did seem to take longer than prior releases at
determining what devices are connected to a system. If one typed in
"dmesg", you'd see more dithering about before devices become ready for
use. I haven't noticed that so much over the last few days.

Don't send private replies to my address, the mailbox is ignored. I
read messages from the public lists.

you may have a look at:

https://bugzilla.redhat.com/show_bug.cgi?id=446845

and

https://bugzilla.redhat.com/show_bug.cgi?id=451579


It has been introduced some kernel update ago and affects f7, f8 and f9
