But on opteron machine there is some problem in kernel compilation at make install stage I am getting following warning WARNING: No module mptbase found for kernel 2.6.13, continuing anyway WARNING: No module mptscsih found for kernel 2.6.13, continuing anyway now when I boot my kernel, panic is received Booting the kernel. Red Hat nash version 4.1.18 starting mkrootdev: lable / not found mount: error 2 mounting ext3 mount: error 2 mounting none switchroot: mount failed : 22 umount : /initrd/dev failed : 22 kernel panic - not syncing : Attempted to kill init On the other hand when I complie same source code on XEON machine this works fine. what could be the problem?
