problems loading gentoo

i'm having trouble booting a gentoo install (as secondary distro), it gives me a

Code:

VFS: Cannot open root device "hda3" or unknown-block(0,0)
Please append a correct "root="
kernel panic...

Gentoo is on a reiserfs partition. My gentoo boot section of my menu.lst is:

Code:

title=Gentoo Linux 2.6.15-server-r2
root            (hd0,2)
kernel          /boot/kernel-2.6.15-server-r2 root=/dev/hda3
savedefault     0
boot

My gentoo root is (hd0,2) also known as /dev/hda3, it is all in a single partition. The kernel boots up fine, up until it has to load the root partition, which then it just borks on me. I have compiled in reiserfs support in my kernel (it's the same kernel configuration on my debian partition which works like a charm). Any ideas?

Did you generate the kernel manually or using genkernel. Ages ago I had the same problem but with slackware (now I've moved on to gentoo and it's the best move I've ever made). Anyway the problem was I had reiser support compiled as a module in the kernel, which causes this kernel panic (or a very similar one) so perhaps you need to compile reiser support into the kernel.

No i'm using my compiled kernel (need built in SCSI card and RAID0), have also compiled in reiserfs, i mean i see all the reiserfs output just fine, but when it switches to the root it screws up. I'm going to look at my kernel configuration to see if there is anything i could be missing...

EDIT: well i should of thought of this before, recompiling the kernel to include my IDE support, sigh stupid mistake...
