hi,

I had similar/same problem booting OldWorld mac and the patch from Olaf fixed it.

The box is: PowerComputing PowerTower Pro
cpu		: 604e
clock		: 195MHz
revision	: 2.2 (pvr 0009 0202)
bogomips	: 448.92
machine		: Power Macintosh
motherboard	: AAPL,9500 MacRISC
detected as	: 16 (PowerMac 9500/9600)
pmac flags	: 00000000
L2 cache	: 1024K unified
memory		: 128MB
pmac-generation	: OldWorld

Situation before patch with 2.4.21-pre5:

0> boot fd:vmlinux.coff
tsize=5880 dsize=139780 bsize=21500 entry=500000
SECTIONS:
.text 00500000 00500000 00005880 000000D4
.data 00505880 00505880 00139780 00005954
.bss  0063F000 0063F000 0002150C 00000000
loading .text, done..
loading .dataCLAIM failed
ok
