Hi;
      I use the above software, apply linuxppc-2005-03-06-2006-02-15.patch
from http://mpc8260sar.sourceforge.net/, `make PQ2FADS_config`, not using
devfs and never manage to boot the kernel:

      I have tried console=ttyCPM0,115200n8 console=tty0 and it makes no difference. BTW, which one should be used for serial console in 2.4.x kernel
for this PowerQUICC II 8280 platform? ttySx or ttyCPMx?
      Any insight is appreciated.

TEH
