Unable to open an initial console - FC3 and vanilla kernel

[Marcin Zajączkowski <mszpak@xxxxx>]

Hi,

I have problems with create bootable vanilla kernel with FC3. Kernels 
contained in Fedora works fine, but I like to have custom kernel 
compiled by myself. With FC2 and below I hadn't any problems. With FC3 
I've got:
Unable to open an initial console
few SELinux messages and freeze booting proccess.

I've found few messages about it and problems with udev, but most of 
them says that I should be able to do it with enable initrd 
(http://www.redhat.com/archives/fedora-test-list/2005-March/msg00022.html). 
Unfortunately it doesn't work for me.
I have 2.6.11.3 original kernel source.

My grub config:
title Fedora Core 2.6.11.3acpi
  root (hd0,2)
  kernel /vmlinuz-2.6.11.3acpi ro root=/dev/hda6
  initrd /initrd-2.6.11.3acpi.img

Do you have any idea what else should I do?
Marcin
