Thanks for posting (I also =E2=80=99ve both boards available),=20
so we can assume that=E2=80=99s an (known) RPI4-only issue, which I also =
encounter when compiling to=20
GENERIC-NODEBUG(or whatever kernel)  to  r357335 yesterday.
I discussed that with Kyle Evans in :=20

That was a copy/paste-issue because I was watching football the same =

The rescan seems to fail... so that if you were on mountroot > -prompt   =
it probably wouldn=E2=80=99t be help to mount=20
by ufs:/=E2=80=A6.    =20

 But I=E2=80=99ve read somewhere that 1 user had success by mounting =
mmc/uSD by typing ufs:/=E2=80=A6 @mountroot

When I waited a moment after the mount-crash it gave me the mountroot> =
prompt on RPI4 but with me no way to mount manually at the moment, so =
this issue has to be fixed =E2=80=A6.


I have updated the Wiki a little( and will add more today) :
https://wiki.freebsd.org/arm/Raspberry%20Pi
.. welcome there  if you have interesting news=20
