Which image did you use (please provide the URL) and what partition layout
did you use? I'm surprised that the root filesystem is referenced with the
device node name (/dev/sdb2) and not the UUID of the partition which has
been standard on Debian for a long time.
Also, why does it try to mount the filesystem on /root and not /? Did you
modify the partition layout and /etc/fstab yourself by any chance? Can you
post your /etc/fstab?

Those instructions were introduced with the SPARC T4 CPU, as far as I know:

Mounting /dev/sdb2 on /root sounds very strange and not something that I would
expect when automatic partitioning is used in debian-installer.
