Ubuntu no longer likes to mount me

I started an edgy eft (Ubuntu 6.06) to feisty fawn (Ubuntu 7.04) upgrade at the weekend. All seemed to go well apart from, it no longer likes my fstab file for auto mounting disks. I have my home directory on a different partition and auto mount it using the fstab file. It no longer works. I spent about an hour trying to figure out why but to no avail. I can see the parition in /dev fine (/dev/sda2) but when I mount it – there’s nothing there. I’ll try with a live CD (I have to unplug one of my monitors first). Has anyone had any issues like this?
