So I had another go at this...

nope:

Ok, I've build a 11.1 kernel using the following configuration:

$ cat /usr/src/sys/amd64/conf/CUSTOM
include GENERIC
ident CUSTOM
nodevice mmc
nodevice mmcsd
nodevice sdhci

This kernel is indeed capable of mounting the root filesystem on my ZFS poo=

So your guess that base r318197 is not actually the cause of this, but mere=
ly
exposes the issue is probably spot on.

12.0-CURRENT not exhibiting the issue raises the question if the underlying
problem is fixed there, or just happens to not be triggered.  Is there a way
for me to provide more information on this?  Maybe boot with
kern.geom.debugflags set to some appropriate value?
