Hi!

Some minutes ago I cross compiled a complete new sparc kernel and
userland for my ipx. Every thing went fine so far...

But booting stops now with:

  NetBSD 1.6ZE (SUN) #0: Sun Nov  2 23:06:35 MET 2003
  	  kilbi@qie:/sys/arch/sparc/compile/SUN
  total memory = 65436 KB

A kernel one day ago seems to work fine:

  NetBSD 1.6ZE (SUN) #3: Sat Nov  1 09:43:05 MET 2003
          kilbi@qie:/usr/src/sys/arch/sparc/compile/SUN
  [...]

Any hint?

Markus.
