Hi @seth-arnold,

adding some details to this bug:

 dn->dn_type = 19 = DMU_OT_PLAIN_FILE_CONTENTS
 dn->dn_type = 20 = DMU_OT_DIRECTORY_CONTENTS

So they look correct, they seem to be just plain files and directories.

However, the specific object that is causing the panic seems to have dn_type=32 that is DMU_OT_DSL_PERMS (that's a bit odd, I don't see any other object types like this in your dmesg), moreover the output of "zdb -dddd" shows a lot of UNKNONW stuff (checksum and compression type for example, they are UNKNOWN).

So, it seems that we may have some corrupted data here.

Do you see any error if you try to run a simple `zpool status -v`? Do you know exactly which pool / volume / filesystem is causing this problem?
