I am seeing this LOR on 8-STABLE (with the latest iwn(4) patches from
the site above).

Do you mean "lockup" as in the system becomes non-responsive?  If so,
I am experiencing this as well.

I recently switched my filesystem to ZFS because of the time fsck_ufs
takes, and added the following options to GENERIC to try to track this
down:

KDB
DDB
BREAK_TO_DEBUGGER
ALT_BREAK_TO_DEBUGGER
INVARIANTS
INVARIANT_SUPPORT
WITNESS
WITNESS_SKIPSPIN
SOCKBUF_DEBUG
DIAGNOSTIC
SW_WATCHDOG
DEBUG_VFS_LOCKS

The last time the system locked, I wasn't in X.  I saw the following
on the console before it became unusable:
