However, it uses taskqueue(9) to schedule the bottom-half handler. This can lead to a panic since the taskqueue(9) code isn't aware it's being called from an NMI context and uses the regular scheduling interfaces. Fix this by scheduling the bottom-half handler using swi(9) and the SWI_FROMNMI flag.
