[11:07] <WeiJunLi> ive compiled ubuntu kernel and now i updated grub but when i try to boot i have this issue http://imgur.com/a/hXjuk ? hints pls 
[13:08] <ogra_> hmm, building an initrd with a non numeric version (i.e. you want an initrd being called initrd.img-debug without containing modules) results in scary "depmod: ERROR: Bad version passed debug"  ... i wonder how hard it would be to turn that rather into "WARNING" so it looks less scary
