Yes, knew that (you can look back at the old thread on tech-kern,
from mid August, subject "EINVAL from copyin/out - how?" to see as
much as was worked out then (which was not much).

I have been expecting that the EINVAL comes from a fault, so far I have
no idea what might be causing it.

What are you uiomove'ing from?  (that is, what is the source?)  Where
does the map for that get set up?
