Mounting new partition on Fedora boot

So far I have mixed feelings about Fedora. Good feelings come from the fact that it is a fully featured yet only Free Software distro, that it has some of the newest things like GNOME 2.16 and overall looks quite nice. However, bad things are slowness of yum, bad fonts in Firefox and the topic of this thread.

Fedora punishes me hard for trying to change mount a new partition automatically at boot, it freezes on boot.

First I tried adding a new partition to be mounted in fstab:

LABEL=/mnt/data             /mnt/data                   reiserfs    defaults        0 2

The label is correct. I later made sure the numbers are the same as I had it on Ubuntu (where it works), but it kept freezing on boot. Right now I just don't know the solution to this.

Then I thought ok, if it wont do it via fstab, I'll just put it in rc.local and mount it on boot this way (at least temporarily until I find the cause of the fstab problem)..

mount /dev/hda4 /mnt/data

That too caused the boot to freeze.

Considering how easy it is to do this on any other distros I've tried, I'm left wondering just what's wrong with Fedora?
