lock order reversal (2 different items)

[Nick H.]

Has anyone come across this before?

dc0: promiscuous mode enabled
Jun 20 09:56:15 router kernel: dc0: promiscuous mode enabled
lock order reversal
 1st 0xc05a0100 bpf global lock (bpf global lock) @
/usr/src/sys/net/bpf.c:375
 2nd 0xc1f5d7bc dc0 (network driver) @ /usr/src/sys/pci/if_dc.c:3543
dc0: promiscuous mode disabled

--this happened when I did a tcpdump -nnxXv for my dc0 interface.

I also got this one on boot today (gg cable company):

lock order reversal
 1st 0xc1fb65c0 process lock (process lock) @
/usr/src/sys/kern/kern_descrip.c:2112
 2nd 0xc200ac34 filedesc structure (filedesc structure) @
/usr/src/sys/kern/kern_descrip.c:2119
swapon: adding /dev/ad0s1b as swap device

--Noticed it on boot, figured it'd be worth a mention

It only happens one time per boot (which isnt often).  Here's some stats on
it:

As you can see, the sources are fairly new (Jun 14th is the last time I
grabbed and built them).

If anyone has any ideas/suggestions or if you need anything more off of me
(Im sorry, Im fresh out of money to give out) ;) I'll be more than happy to
provide with what I can.  Thanks!
