Gang,
A couple of weeks ago I delayed the creation of an install image from
our development branch because the EFI loader was causing a general
exception. I tracked it down to a bogus call to netif_put(). This is
what I see with some debug information:
\begin{verbatim}

\end{verbatim}
We seem to call netif_put in this particular case even though we're
booting from fs0. The desc argument appears valid, but the structure
is probably not initialized. This is likely the result of booting
from fs0, because on this machine we can perform a netboot without
problems (that's how I ended up installing FreeBSD on it anyway).
On my BigSur I don't see any calls to netif_put() when booting from
fs0, so the bug is likely in calling netif_put().
Knowing this, I should have a fix soon...
FYI,
