>Description:
About 4 TB into a zfs recv the kernel panic'd with "lock &arg.lock already initialized".
core.txt available.

>How-To-Repeat:
Receive large (10 TB) recv where the replicatiiion stream contains many filesystem deletes & rename. Filesystem deletes and renames seem to cause more problems.
>Fix:
None
