I have taken out the PCI initialization code:

[root at ShrekII linux 4]# grep PCI .config
# CONFIG_PCI is not set
# CONFIG_DMA_NONPCI is not set
# CONFIG_NET_PCI is not set
[root at ShrekII linux 5]#

Here is the log_buf:

[root at ShrekII linux 3]# grep log_buf /fadsroot/boot/System.map
c01d40b4 b log_buf
[root at ShrekII linux 4]#

Here is what is in the log_buf after the system reboots when booting the linux kernel:

I can't see any helpful information in this log_buf....:-<

Any insight is appreciated.
