The log is attached. I'm not sure what exactly is going on here. The
conditions were: building something on zfs, while also accessing files over
NFS. It seems each of those individually is fine, but doing both it brings
my system down. I _think_ the actual panic message (recursed on
non-recursive mutex) is a red herring, since it already trapped in the
kernel, twice. Any clues? It's 100% reproducible by me.
