I am using RHEL5.
and I have below too in my .config.
CONFIG_SYSFS_DEPRECATED=y
CONFIG_SYSFS_DEPRECATED_V2=y
My /etc/modprobe.conf has the following
alias scsi_hostadapter ahci
alias eth2 ixgbe
alias eth3 ixgbe
Do I need to add the below lines in /etc/modprobe.conf ??
# RHEL -> FC11 quick upgrade path.
grep -q xenfs /etc/fstab || echo "xenfs /proc/xen xenfs defaults 0 0" >> /etc/fstab
if grep -q ata_piix /etc/modprobe.conf ; then
NR=`cat /etc/modprobe.conf | grep scsi | wc -l | sed s/[[:space:]]*//`
grep -q pata_oldpiix /etc/modprobe.conf || echo "alias scsi_hostadapter$NR pata_oldpiix" >> /etc/modprobe.conf
fi
grep -q hvc /etc/inittab || echo "co:2345:respawn:/sbin/agetty hvc0 9600 vt100-nav" >> /etc/inittab
grep -q hvc0 /etc/securetty || echo "hvc0" >> /etc/securetty
Could you please let me know what exactly needs to be done? I could not get much out of it?
Thank You.

Hmm, Are you using a RHEL5/CentOS based userspace to build the initrd image?
If you are please take a look at this:
