given that cpu0 is dead, you might get some life out of it
in the interum before getting a replacement by simply
physically swapping cpus

Hello fellows,
I have a dual PowerMac G4 (described below in /proc/cpuinfo) and for a
few months it has presenting some problems. When I am operating the
machine, is presented in gkrellm that the processor #1 stops
operating. This crash presents two different scenes: (1) the processor
#1 stops but the processor #0 operates normally, supporting all
amount of work; and (2) the two processors stops and I need reboot the
machine.
I'm using the kernel version 2.6.8 and this same problem occur in
other kernel versions and in Mac OS X, too.
Verifying /var/log/messages, I can see this anormal message:

/var/log/messages:
May 30 11:20:23 falcao kernel: Machine check in kernel mode.
May 30 11:20:23 falcao kernel: Caused by (from SRR1=20009030): L1 Data
Cache error
------------------------------------------------------------------------------------
I did some searches using Google, but I didn't find a solution for
this problem. I suppose disabling the processor #1, I can solve this
problem. So, how can I disable one of my dual processors?? Or, how can
I solve this problem :-D ??
Looks like one of your processors is indeed broken. Try booting with
maxcpus=1 on the kernel command line (and hope that's not CPU0 that is
dead).
Ben.
