I`ve just bought a new machine preconfigured with Ubuntu 7.1. Since I
can`t get an answer from the vendor atm though i`d try here.

My machine has a DVD re-writer which works ok and a dvd rom drive which is
causing problems. it may be as simple as a duff peice of hardware but it
sends Ubuntu crazy.

Often the drive just won`t recognize a disk, sometimes it does but often
Ubuntu will freeze for 20-30 seconds or so before briefly releasing the
mouse (maybe long enough to reboot).

In case its a config problem i`ve pasted the etc/fstab below (I was
suprised to see hda and hdb being used for the dvd drives on my old debian
setup these were used for the HD`s , is this normal?).
