If you're new to building kernel, it will take some time to learn what modules you need what options you should enable, etc. You're building gentoo on some host Linux os, so you can use that os's lsmod utility to know what modules you require. Also, if some modules may be compiled right into the kernel you may not be able to see them in the lsmod produces, instead use lspci -v for that. One important thing I learnt the hard way while building gentoo for a server- Always compile the critical modules like disk controllers, RAID, also don't forget to use RAID autodetection if you're not going to use an initramfs and filesystems (involved at boot) statically. While citing my experience about building gentoo on a server, you have to do the things invisibly, so you can't see what the kernel emits befor panic. It turned out that I'd disabled RAID autodetection and wasn't using an initramfs either (which will load the arrays using mdadm). -- Nilesh Govindarajan http://nileshgr.com
