Problem:

I can not create initrd.img for kernel 2.6.18-53.* (SP1 maintenance kernel), I get the following error message:

No module dm-mem-cache found for kernel 2.6.18-53.*, aborting

Solution:

Please add the option “--without-dmraid” when creating initrd.img. See below:

mkinitrd --without-dmraid /boot/initrd-2.6.18-53.23AXS3.img 2.6.18-53.23AXS3
