MPC8260 Reset Status: Check Stop, External Soft, External Hard


      I have tried console=ttyCPM0,115200n8 console=tty0 and it makes no

difference. BTW, which one should be used for serial console in 2.4.x
kernel

quoted

for this PowerQUICC II 8280 platform? ttySx or ttyCPMx?
      Any insight is appreciated.

The right thing is ttyS0 for 2.4.x...
First, if that will not help, I suggest to comment out the PCI

initialization code, and to see if it will help.

I have taken out the PCI initialization code:

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

Here is the log_buf:

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