No idea why it's affecting your serial console though - the autoconfig should be transparent once it's completed. Sure, if you enable serial debugging (thereby making it produce output during the autoconfig) it will mess it up, but that's the standard gun and foot scenario. -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of:
