Hi Eric,
I have tried numa=fake=4 on intel xeon with 2.6.13 kernel it is
working fine and by adding EXPORT_SYMBOL(pgdat_list) in
mm/page_alloc.c now I am able to access pgdat_list also. 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?
Hi Devesh
I believe you have basic kernel compilation problem :)
Your kernel cannot mount / because the boot loader was configured to find a
root=LABEL=/
As this is a RedHat kernel extension, your self compiled 2.6.13 kernel cannot
understand this.
You should change your lilo/grub config to match your root device as
root=/dev/hda2 (if hda2 is your root device)
Also check that your kernel (or initrd) contains the disk driver you need.
Eric
