what version of freebsd ?

if you're on freebsd 4.x, you'd need the following patch to the 4.x branch 
sources of the wct4xxp.c driver, as the current macro expansion for 
DECLARE_MODULE/MODULE_DEPEND needs t4_load() defined before it works. 
without this patch, a kldload would panic the system.

in addition, i'm investigation a condition where the use of 
INTR_TYPE_FAST/INTR_FAST would cause a kernel panic if shared interrupts 
were present. this can be avoided (i think !) by removing the RF_SHAREABLE 
flag in the call to bus_alloc_resource(). i've noticed that adding 
INTR_TYPE_FAST on freebsd 4.x with shared interrupts will cause a kernel 
panic when asterisk is started, though kldload and ztcfg go ok.

the freebsd driver docs state that INTR_TYPE_FAST can only be used when 
interrupts are not shared.
