So the other report of increasing de-assert from 10ms to 50ms is needed for success of the debian-installer hwprobe detection, and this here issue of adding to the 'compatible' is needed for success of rmmod/modprobe cycling. In concert together both fixes resolve all of the trouble I observed and reported, tested and verified on Sipeed K3 Pico ITX. Thanks for tracking this down it is very much appreciated :) With that, Tested-by: E Shattow
