RAID Ctrl and generic kernel

I have Fujitsu RX300 S7 server and LSI RAID Ctrl SAS 6G 1GB D3116 Contoller.

01:00.0 RAID bus controller: LSI Logic / Symbios Logic MegaRAID SAS 2208 [Thunderbolt] (rev 03)
I have successfully installed Slackware 14 x86_64 on this server and booting fine with huge kernel (3.2.45).
But booting with generic kernel not work.

RAMDISK: Couldn't find valid RAM disk image starting at 0.
VFS: Cannot open root device "803" or unknown -block (8,3)

I have created ramdisk with this command
mkinitrd -c -k 3.2.45 -m megaraid_sas:reiserfs -o /boot/3.2.45-initrd.gz -s /boot/3.2.45-initrd-tree
lilo -v
no warnings

You missing FS driver
Try this

mkinitrd -c -k 3.2.45 -f reiserfs -r /dev/YOUR_DEVICE -m megaraid_sas:usbhid:ehci-hcd:uhci-hcd:mbcache:jbd2:ext4:reiserfs \
-u -o /boot/initrd.gz

There is a wonderful tool in

you can invoke it this way:

# ./ -k 3.8.13
and it puts out with lot of magic something like this:

mkinitrd -c -k 3.8.13 -f ext4 -r /dev/sda1 -m usbhid:uhci-hcd:mbcache:jbd2:ext4 -u -o /boot/initrd.gz
wich is the right initrd for my computer.

This not helped me


mkinitrd -c -k 3.2.45 -f reiserfs -r /dev/sda3 -m megaraid_sas:usbhid:ehci-hcd:uhci-hcd:mbcache:jbd2:ext4:reiserfs -u -o /boot/initrd.gz
And this also

mkinitrd -c -k 3.2.45 -f reiserfs -r /dev/sda3 -m megaraid_sas:usbhid:ehci-hcd:reiserfs -u -o /boot/initrd.gz

Than, you might need to rebuild kernel, if you don't want to use huge.

Are you sure to use the right initrd in lilo.conf? Have you issued it?
