boot problems on g4

[crisbill <crisbill@pop.lightlink.com>]

I'm trying to install Debian on a G4 using the current linux and
root.bin from Woody (3.07-2001-07-11). I've placed these files on my Mac
harddisk, along with yaboot 1.2.3.
Booting gets stuck, with these kernel messages:
----------------------------------------------------------
md driver 0.36.6 MAX_MD_DEV=4, MAX_REAL=8
Machine check in kernel mode. (regs at c1ebf9d0)
Caused by (from srr1): Unknown values in srr1
NIP: C013A408 XER: 20000000 LR: C013C0A8 REGS: c1ebf9d0 TRAP: 0200
MSR: 00009030 [EE,IR,DR,ME]
TASK = c1ebe000[1] 'swapper' mm->pgd c01e4000 Last syscall: 120

....[ Lots more numbers, call backtrace, etc]

kernel panic: machine check
----------------------------------------------------------
Does this suggest anything to anyone?

Thanks,
