Hi,
I am able to boot linux kernel 2.6.12 on ppc 8540, and also able to login
too. But then i am unable to see any output when i say ls, mount,ifconfig
etc. Only pwd and env seem to work
Whereas if i boot with kernel 2.4.20 and with the same ramdisk which i
used to boot 2.6.12, i am able to see eveything, ls, mount outputs etc.
I built the ramdisk image using busybox 1.2
This is the boot messages of 2.6.12 :
