<br><font size=2 face="sans-serif">Hi,</font>
<br>
<br><font size=2 face="sans-serif">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</font>
<br><font size=2 face="sans-serif">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.</font>
