Grrr, forgot the trap information: From source cvsup on 6/23/99, the kernel traps on boot near sc0. I tried every variation of the kernel I can think of, including GENERIC, and same thing. I finally changed to vt0 and it booted up fine. I am using the standard sio0 config with the 0x10 flag and a /boot.config file with "-h".
