Before I get to the "good stuff", I'll note that:
* I'm no longer running a VIMAGE kernel, so that possible source of
confusion should be absent.
* The hardware in question (a miniPCI device in my laptop) has been
working under stable/7 and stable/8 (so I believe that there should be
nothing so wrong with the hardware that it should cause a panic).
* I tend to see a lot of messages: "iwi0: firmware error" -- especially
running CURRENT. I have seen a few of them while running stable/7, as
well (but no panics under stable/*).
* An ath(4) PCcard works fine (now that I'm not running VIMAGE).
* uname reports:
FreeBSD g1-219.catwhisker.org. 9.0-CURRENT FreeBSD 9.0-CURRENT #80 r210841:=
Wed Aug 4 08:34:39 PDT 2010 root@g1-219.catwhisker.org.:/usr/obj/usr/=
src/sys/CANARY i386
(though sources were actually updated to r210855 just prior to this
norning's build).
I've attached a opy of the core.txt file; here's the backtrace:

So it seems that IWI_STATE_BEGIN kcked up a fuss; it's a macro,
defined in sys/dev/iwi/if_iwivar.h:
#define IWI_STATE_BEGIN(_sc, _state) do { \
KASSERT(_sc->fw_state =3D=3D IWI_FW_IDLE, \
("iwi firmware not idle, state %s", iwi_fw_states[_sc->fw_state=
]));\
_sc->fw_state =3D _state; \
_sc->sc_state_timer =3D 5; \
DPRINTF(("enter %s state\n", iwi_fw_states[_state])); \
} while (0)
So.... maybe that "firmware error" isn't so benign after all? I'm
not exactly sure what I can actually do about it (and still use the
device)....
Clues? I'm happy to hack a bit & test, given guidance....
Peace,
david
