I recently decided to update my AMD64 box from 2.38 to the new 3.2 kernel.
I used genkernel all to compile the upgraded kernel but when I go to boot
I get the following error.
>>Loading modules
>>Determining root device
!!Block device /dev/sdb2 is not a valid root device
!!Could not find the root block device in .
Pleas specify another value or" press enter for the same, type "shell" for
a shell, or "q"to skip..
root block device()::
However at this point the computer is hung and I am no longer able to
input anything. I just switched over to gentoo from bsd a year or so ago
and am still a newbie at some of the installation procedures but I believe
I have followed the manual correctly with the only change being that /boot
is located on the root partition and not a seperate partition. I'm still
able to use my older kernel without a problem and the only difference that
I can note between the two is that older kernel seems to load in a bunch
of modules and starts mdev, I believe, before trying to locate root. I am
also using Lilo since my motherboard doesn't seem to like grub. Any help I
could get would be appreciated.

storage
