Use labels so there are no static device names at all.  With MBR, the 
options are limited, but UFS labels work and have no metadata problems:

GPT has very nice partition labels that can be set with gpart -l.  It 
works with i386 and BIOS booting.

The SATA subsystem was changed to use cam back in 2012 [1], which
changed device numbering from adX to ada0, ada1.

Back then, a sysctl called kern.cam.ada.legacy_aliases, which is
enabled by default, was provided for backwards compatibility.

Some research shows that this feature was removed in r289137 [2]

It's also covered in UPDATING:

20151011:
Compatibility shims for legacy ATA device names have been
removed. It includes ATA_STATIC_ID kernel option,
kern.cam.ada.legacy_aliases and kern.geom.raid.legacy_aliases
loader tunables, kern.devalias.* environment variables, /dev/ad*
and /dev/ar* symbolic links.

no, but now and it worked; I will adjust /etc/fstab; but why is this?

And then 'make installkernel KERNCONF=GENERIC' I suppose.

Did you try ufs:/dev/ada0s1a?

i386;

yes, clean 'make buildkernel KERNCONF=GENERIC'

interestingly: I can type at the prompt 'mountroot> ' into the dark and
always when I press Ctrl the chars are written to the screen and so I can
specify 'ufs:/dev/ad4s1a' which than leads to the same error 19.

I can as well boot an USB key with the old kernel r269739, mount
/dev/ad4s1a to /mnt, all fine; I did even a fsck while booted from USB
on /dev/ad4s1a. The FS is clean.

Hi Matthias,

Did you try to connect an external USB keyboard?
i386 or amd64?
Did you do a full clean build?
GENERIC or custom kernel config?

short before mounting root are two error messages:

taskqgroup_adjust failed cnt: 1 stride: 1 mp_ncpus: 1 smp_started: 0
taskqgroup_adjust failed cnt: 1 stride: 1 mp_ncpus: 1 smp_started: 0
Timecounter "TSC" frequency 1596219540 Hz quality 1000
Trying to mount root drom ufs:/dev/ad4s1a [rw]...
mountroot: waiting for device /dev/ad4s1a ...
Mounting from ufs:/dev/ad4s1a failed with error 19.

Than it goes into the manual dialog to specify the root device but at
the prompt 

mountroot>

the kernel does not echo any typed chars;

r300951: mountroot: waiting for device /dev/ad4s1a...

[Matthias Apitz]

Hello,

I'm trying to update my laptop Acer Aspire One D250 from r269739 to
r300951. After 'make installkernel' it hangs for ever on reboot, waiting
for the device /dev/ad4s1a. The old kernel boots fine.

What can I do?
Thx
