Hi all, I am trying to upgrade my kernel from 2.4.18-14 to 2.5.70. the following steps i did. 1.after choosing the options i gave make bzImage and it went fine. 2.make modules...it deselected unnecessary modules and this also went fine. 3.then i gave "make modules_install" .i got lot of errors saying depmod:warning "unresolved symbol" blah blah and then inside /lib/modules/2.5.70/ i cud see .ko files. and no .o files. a) what are those .ko files ? b) my system being RH8.0 it requires initrd and how do i get the initrd file working' for this i tried #mkinitrd --with=ext3 initrd.img 2.5.70 i got the following error unable to find module mbcache tools used GCC - gcc-3.2-7 mkinitrd - mkinitrd-3.4.28-1 was anybody successful in doing this upgrade ?.i also did some googling but was in vain :( Thanx in Advance.
