--- Comment #24 from Mark Millard <marklmi26-fbsd@yahoo.com> ---
(In reply to pascal.guitierrez from comment #11)

If you can test main , stable/14 , or stable/13 , then
testing with:

nullfs_load=3D"YES"
vfs.nullfs.cache_vnodes=3D0
zfs_load=3D"YES"

in /boot/loader.conf could prove interesting. vfs.nullfs.cache_vnodes
has been MFC'd but no releng/* has it yet.

nullfs.ko is what adds vfs.nullfs.cache_vnodes , thus the the explicit
load as early as possible, just before the assignment. In my context I
got:

# kldstat
Id Refs Address                Size Name
 1   84 0xffffffff80200000  1d497b0 kernel
 2    1 0xffffffff81f4a000     9810 nullfs.ko
 3    1 0xffffffff81f55000   5e8fe0 zfs.ko
 4    1 0xffffffff8253e000     7718 cryptodev.ko
. . .
