I finally got around to hooking up a serial console to my Miata
(never throw your terminal servers away ;)
Anyway:
isp0: interrupting at CIA irq 3
fpa0: <Digital DEFPA PCI FDDI Controller> port 0x8100-0x817f mem
0x80800000-0x8080ffff,0x80821000-0x8082107f irq 16 at device 9.0 on pci1
fatal kernel trap:
trap entry = 0x2 (memory management fault)
a0 = 0x80821014
a1 = 0x1
a2 = 0x0
pc = 0xfffffc0000369158
ra = 0xfffffc0000368e98
curproc = 0xfffffc000057e988
pid = 0, comm = swapper
ddbprinttrap from 0xfffffc0000369158
ddbprinttrap(0x80821014, 0x1, 0x0, 0x2)
panic: trap
panic
Stopped at Debugger+0x2c: ldq ra,0(sp) <0xfffffc00005e5900>

and
fffffc00003688e0 T pdq_interrupt
fffffc0000368c20 T pdq_initialize
fffffc00003691c0 T pdq_ifinit
fffffc0000369300 T pdq_ifwatchdog
fffffc0000369380 T pdq_ifstart
fffffc0000369520 T pdq_os_receive_pdu
fffffc0000369620 T pdq_os_restart_transmitter
It seems something in pdq_initialize might be doing something wrong. At
least, it does on alpha. I tested with one DEFPA in a current i386 FreeBSD
box and the other one in the Miata running T64 4.0G. That works just fine.
Ideas?
