Chage it to 9. 9 is printk_spew
However I just looked at the epia-m auto.c main() and the serial port
is not enabled until _after_ enable_smbus(). So something in your
smbus may be hanging things up until it times out.
in epia-m/auto.c comment out line 124, enable_smbus() and re-run.
With loglevel 9 you should get the "In auto.c main()" message pretty
quick. If that works then try moveing enable_smbus() to after the
If that crashes or hangs then you will have to leave it alone and
debug code prior to main() and find out where its looping to cause the
Look at southbridge/via/vt8235/vt8235_early_serial.c to see how to
send messages out the serial port.
