I get this error when i try to boot gentoo 1.4. I did a stage 1 install
with no problems, kernel compiled without any errors. My boot partition is
ext3 and my root partition is reiserfs. this is the last line i get before
my system stops booting.

kernel panic:vfs:unable to mount root fs on 3:07

(i am unsure of the last number i need to check again) i will be checking
again for the rest of the lines around it once i get home. thanks for the
help.

Check that you compiled reiserfs into your kernel, not as a module

Probably you didn't edit your boot loaders config file properly or you
didn't provide the 'root=/dev/hdxy' kernel parameter. can you post the
output of 'cat /boot/grub/grub.conf' if using grub or 'cat /etc/lilo.conf'
if using lilo and also 'cat /etc/fstab'?

The kernel must support the filesystem on your root directory without
needing any modules. If the kernel needs a module it will not have
any filesystem from which to load it. Catch 22.

Or you can use an Initial RAM Disk, but it is much easier to simply
compile the appropriate file system into the kernel.
