I describe an uname output by hand because this kernel cannot boot up.
NetBSD shloeder.tenjin.org 2.0G NetBSD 2.0G NetBSD 2.0G (SHLOEDER) #19: Mon Sep  6 10:14:13 JST 2004        kawamoto@linus.ics.es.osaka-u.ac.jp:/var/obj/var/src/sys/arch/macppc/compile/SHLOEDER macppc

>Description:
After wdc structures clean-up at Aug 15 2004, my iBook G4 cannot boot.
A wdc controller of a GENERIC kernel cannot probe an internal harddisk as 
wd0, and after some moments, the kernel prompts to request a root device.
The kernel before Aug 15 2004 can probe wd0 and boot normally.
Kernel messages are followings:
