Subject:   debugging fpa / FDDI panic

Now that I have -current running on my Miata I'm trying to find out why the
fpa driver causes a panic on boot:

isp0: interrupting at CIA irq 16
pci1: <network, ethernet> at 10.0 (no driver attached)
fpa0: <Digital DEFPA PCI FDDI Controller> port 0x9000-0x907f mem
0x80950000-0x8095ffff,0x80960000-0x8096007f irq 4 at device 11.0 on pci0

fatal kernel trap:

    trap entry = 0x2 (memory management fault)
    a0         = 0x80960014
    a1         = 0x1
    a2         = 0x0
    pc         = 0xfffffc0000390698
    ra         = 0xfffffc00003903d8
    curproc    = 0xfffffc00006110a8
        pid = 0, comm = swapper

Stopped at      pdq_initialize+0x538:   ldl     t0,0(t0) <0x80960014>

I'd like to cause a dump, but 'panic' does not want to do that for me.
I'm not much of a DDB guru, and appreciate a helping hand  here.

Tnx
