I am configuring and compiling a new kernel with Netbsd i386 1.2.1 and would
like to know if first I am going thru the right sequence and second if
anyone knows why the system hangs shortly after booting on the line shown.

The config and compile sequence: 

# cd /usr/src/sys/arch/i386/conf
# config GENERIC
# cd ../compile/GENERIC
# make depend && make
# mv /netbsd /netbsd.old
# cp netbsd /
# reboot

Where the system hangs after booting:

sea0: board type unknown at address 0xf8351000

The changes I have made in the kernel are minor (they are in scsiconf.c and
st.c) to try to get a TK50GZ tape deck to run on scsi.  Also the size of the
new kernel seems to be about twice the size of the original.  

Any Ideas, suggestions!
