I found out that the problem may be caused by autofs, which is used to automatically mount file systems such as cds or nfs shares whenever they become available, as such, if you havn't started autofs intentially, you should stop it starting at boot to fix the problem, here's how ...
Another solution is to kill NFS if you don't need it, this can be done in the mandrake control center,
> system > services , scroll down to nfs and uncheck "start at boot". However the first option of stopping autofs supposedly works so try that first.
I havn't had the chance to try these solutions out yet since i'm at work so if you want i can try them tonight and let you know how it goes or if you do try it out let me know how you go with it.
