While I do not currently use ZFS, the wireless NIC I have been using most often for the last several months has been iwi0 on my laptop, on which I track stable/6, stable/7, stable/8, and head on a daily basis. While I have seen the interface bounce dwn & up repeatedly, and it refuses to communicate with an Apple Airport AP (while working with a Linksys WAP11) under head (but the Airport is OK for stable/6 and stable/7; not sure about stable/8), it has been (at least) several weeks since my last panic, so I am inclined to suggest that iwi(4) and wlan(4) are unlikely to be involved in the root cause of the panic.
