Description

Hello.
Caught this while running pbulk on an Atom D510, running x86_64 kernel.
This one is new to me and I haven't seen this one before updating the
kernel. The current kernel was built from source whose commit hash is
c6aff4f7f0c74961380763de0bcb5dd49fb7faea, while the previous kernel was
from c4ce4f88f289f77826fecf470965d7e216274018. No hammer cleanup was
running when it panicked.

Unread portion of the kernel message buffer:
