Hello there,
             I've tried the above to build a kernel for XFree and also with 
these notes:-

http://mail-index.netbsd.org/port-sparc/2005/10/01/0000.html

The kernel builds fine but does not boot, I get a data error on boot and 
then immediately a watchdog timer reset. My sources are up to date as of 
yesterday the 10/05/2006. Any pointers as to what I should do now?

My dmesg with a standard -current kernel is below, if anyone wants my 
kernel config file please let me know.

Best regards John.
