Can something like this be a valid command?

zdb -d <0xffffffffffffffff>:<0x0>

Guesswork from 
<https://openzfs.github.io/openzfs-docs/man/8/zdb.8.html#EXAMPLES> 
example 3.


Also, taking a hint from <https://github.com/openzfs/zfs/issues/3476> 
and <https://github.com/openzfs/zfs/issues/4736> (but not assuming a 
hardware issue in your case):

zdb -mc zroo2
