Lock order reversal

[Dave Rand]

Has anyone seen this before?

Sep  5 15:06:02 rdaver kernel: lock order reversal
Sep  5 15:06:02 rdaver kernel: 1st 0xcf33ba34 filedesc structure (filedesc structure) @ kern/sys_generic.c:895
Sep  5 15:06:02 rdaver kernel: 2nd 0xc054c640 Giant (Giant) @ fs/specfs/spec_vnops.c:372

I've been getting this regularly.  The above error was generated on a
CVSUP from last night, but has occured on everything I've tried in 5.1.

I'm running about 3T of disk, split into roughly 600G chunks for the bulk,
and smaller volumes for /, /usr, etc.
