Kernel startup problems on p630

[VAKKALANKA RAO Sridhar]

Hello,

I am trying to boot a p630 with a 2.4.21-pre4 kernel. At the console, the output indicates that the "start()" function in "<kernel-source>/arch/ppc64/boot/zImage.c" has successfully completed. Immediately after that, I get the output:


...ok
	rtas at 0x000000003fc88000... done
opened /pci at 400000000110
open success
opened /pci at 400000000112
open success
	(translate ok) returning from prom_init


The screen freezes for several minutes with this display and the machine simply restarts. When it restarts, it reboots with the originally installed AIX 5.1 operating system.

(1) A google search revealed that IBM is aware of this problem for the p670 & p690, but their suggestions were not helpful.

(2) The very same binary, "zImage.initrd", works fine for someone who possesses the very same machine (p630). This person had his firmware level at a lower level than mine. Yet, when I requested our IBM support to restore the older firmware, they refused stating that it wouldn't help at all and that there was no way to access old firmware levels.

Can anyone give me some advise?


Thanks
Sri
