Strange Kernel Errors

Hi,

Just built a new kernel and im getting the following errors during boot, but it still boots and there is no panic, but i would like to fix them if possible, i assume i either built something in i shoundt have, or missed something out

Code:

DMESG Segment:

Are you using nbd? It is an odd duck. You need to have a client on your computer and a server on the remote host:

Code:

   Howto: To setup nbd, you can simply do the following:

   First, serve a device or file from a remote server:

   nbd-server <port-number> <device-or-file-to-serve-to-client>

   e.g.,
        root@server1 # nbd-server 1234 /dev/sdb1

        (serves sdb1 partition on TCP port 1234)

   Then, on the local (client) system:

   nbd-client <server-name-or-IP> <server-port-number> /dev/nb[0-n]

   e.g.,
        root@client1 # nbd-client server1 1234 /dev/nb0

        (creates the nb0 device on client1)

If you aren't using it, you might not want to have the module loaded in the kernel (or did you answer Y instead of M in xconfig?).
