Argg!!!, I think I am stacked with this situation. I compiled
linux-2.6.18-164.11.1.el5.tar.bz2 under Ubuntu 10.04 (from Debian
Squeeze) using make-kpkg and after dealing with postinst.d hooks to
create initrd image (not created by default!!!), I tried to boot and
then I got the following before dropping into a initramfs shell:

---------------------------------------------------------------------------
Begin: Mounting root file system... ...
Begin: Running /scripts/local-top ...
Done.
libudev: udev_monitor_new_from_netlink: error getting socket: Invalid
argument wait-for-root[431] : segfault
Gave up waiting form root device. Common problems:
  - Boot args (cat /proc/cmdline)
    - Check rootdelay= (did the system wait long enough?)
    - Check root= (did the system wait for the right device?)
  -Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/disk/by-uuid/0cff75ed-ba7f-4799-b596-cf2b214b9768 does not
exist. Dropping to a shell!


BusyBox v1.13.3 (Ubuntu 1:1.13.3-1ubuntu11) buit-in shell (ask)
Enter 'Help' for a list of built-in commands.

(initramfs)
------------------------------------------------------------------------------

Is this the problem you are talking about? Could you give me some ideas
of how can be solved?

Regards
