Hello David.

I had the same with r320873. Either my box (a SSD/UFS2-off booting server r=
unning
CURRENT) ended up in a immediate panic and rebooted or it is stuck at=20

[...]
mountroot: Waiting for device /dev/gpt/root ...
Mounting from ufs:/dev/gpt/root failed with error 19

mountroot >: ?

List of GEOM managed disk devices

mountroot >:
[...]

I went back to r320843 as I identified r320844 to be the culprit in my case.

I regret having not more information ...

Kind regards,

Oliver
