Update to 14.3 does not boot anymore

Dear all,

I tried to upgrade today one of my servers from 14.2 to 14.3 using 
freebsd-update.
I just fetch the update, installed new kernel and rebooted:
freebsd-update upgrade -r 14.3-RELEASE
freebsd-update install
reboot

Now I see on the screen:
(ada1:ahcich1:0:0:0): READ_FPDMA_QUEUED. ACB: 60 e0 48 04 04 40 00 00 00 
00 00 00
(ada1:ahcich1:0:0:0): CAM status: Auto-Sense Retrieval Failed
(ada1:ahcich1:0:0:0): Error 5, Unretryable error

this is repeated and server refused to boot.
Maybe the disc is broken, but it worked fine till before the reboot into 
the new kernel, so this can also be related to the upgrade.

These are Exos Enterprise Seagate harddiscs.

Does anyone have an idea?

Gruß
Matthias
