Hello.
  Today I installed daily build (20061126) of NetBSD 4.99.4 on a 
PowerBook 3400c with OF 2.0.1. Sysinst went without problems, but after 
installation I cannot boot anymore:

0 > setenv auto-boot? false
0 > setenv real-base F00000
0 > setenv load-base 600000
0 > setenv boot-device /bandit/ohare/ata/ata-disk@0,0:0
0 > setenv boot-file netbsd
0 > reset-all

After reboot I issued boot command:
0 > boot
OF_open bootpath=/bandit/ohare/ata/ata-disk@0,0
read stage 2 blocks: 0123456. done!
starting stage 2...
DEFAULT CATCH!, code=FFF00700 at %SRR0: 00E00000 %SRR1: 00083070

I looked at PR 27110, and it looks kinda similar.

Before installation of 4.99.4 this PB was running NetBSD 2.0.something, 
and it was quite stable. Unfortunately, now I'm stuck - this PB has no 
onboard ethernet or internal CD. I installed 4.99.4 by booting 
netbsd-INSTALL from existing NetBSD partition. Looks like I have to 
search around for PCMCIA-CompactFlash adapter. I hope booting from 
PCMCIA still works (long time ago I installed NetBSD 1.6.2 this way).
