Can you make sure you have a complete debugging kernel with WITNESS=20 enabled? Setting debug.iwi could also reveal what's going on. =20 Unfortunately it's only a sysctl, not a tuneable, so you'd have to change=20 the default in sys/dev/iwi/if_iwi.c line 88 by hand and recompile your=20 kernel/module.
