How do you have device sio configured in your kernel ? Are you trying to
specify the ports for the puc attached serial ports ? All you need is
device sio
device puc
Also, enable crash dumps and build a debug kernel. Add
makeoptions DEBUG=-g
to your kernel config
and at bootup time add
dumpdev="/dev/da0s1b" # Device name to crashdump to (or NO).
dumpdir="/var/crash" # Directory where crash dumps are to be stored
Assuming your swap is on da0s1b
