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

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
