Gentoo software raid boot problems


Hi!

I hope im posting in the right corner here..

If installed gentoo from a stage3 tarball on my system.
It should run on a software - raid 0 / 1 combination, but i cant boot it gives me a kernel panic (cant mount rootfs on /dev/md2!)

I did:

a two disk set with 3 partitions on each disk combined to a software raid;
md0 as raid1 ext2 for boot (GRUB)
md1 as raid0 swap
md2 as raid0 reiserfs for root

/etc/raidtab is present on /dev/md2, but if i even cant mount /dev/md2 while booting the kernel
so it is useless isnt it?
What could i forget compiling the kernel?

CONFIG_MD is set
CONFIG_BLK_DEV_MD is set
CONFIG_MD_LINEAR is set
CONFIG_MD_RAID0 is set
CONFIG_MD_RAID1 is set
This stuff isnt load as module; its directly loaded into the kernel...
I also did emerge raidtools and reiserfsprogs
Could anyone here imagine what i could forgot?

YOURS

booting soft raid 0

Problem may be that kernel cannot boot directly from software raid partition or disk. I would add new small (ex.64mb) single partition with ext2 filesystem and mount that under /boot.
