Strange initdb error with kernel 2.4: unknown type 'ame'.

Hello !

I'm using postgres quiet succsessfully on RedHat 6.2

I tried to install PostgresQL on the distribution Gentoo
(aviable for free from www.gentoo.org) because I
was curious how PostgresQL would perform on a
2.4.0 based linux system with ReiserFs as file system.
(I tested also with 2.4.1-pre8 kernel with the same results)

All compiled nicely (I used the tarball source version 
7.1beta3, i didn't gave any parameters to configure), 
but i could not run initdb like in my privious 
installations under RedHat 6.2.

This is what happend:

bash-2.04# rm -rf /var/lib/pgsql/*
bash-2.04# su postgres
bash-2.04$ /usr/local/pgsql/bin/initdb -D /var/lib/pgsql
This database system will be initialized with username "postgres".
This user will own all the data files and must also own the server process.
