Raw device works fine - no panic and no deadlock.

Also tested dump with snapshot (56GB partition, 26GB used) from disk to 
other disk:

newfs -O 2 /dev/rld1a
mkdir /mnt/target
mount -o log /dev/ld1a /mnt/target
cd /mnt/target
dump -0uaX -f - / | restore rf -

So far no problems encountered - using CURRENT 20260724074047Z.

If I understand correctly, dump command reads raw device - so that's 
what matters for me - being able to dump snapshot without issues.
