Been consistently getting this same kernel panic since at least B2 or B3 maybe even B1, not sure.
Only when doing SMB to my NVidia shield to copy files on. ( don't have any other SMB1 devices to test against right now to try and establish whether it is unique to shield or smb1 in general )
Usually when finder is expanding a file tree.
I have reported it to Apple, but got no acknowledgement of it thus far.
This is a fairly consistently reproducible full on reboot the machine level kernel panic.
