проблема с DVD-RW

Доброе время суток! Спасите человека, поставившего DVD-RW, а он не хочет работать :-(
Подскажите где искать причину. (все железо до этого прекрасно работало под виндой хр)
При монтировании устройства в dmesg выдает следующее:

process `nslookup' is using obsolete setsockopt SO_BSDCOMPAT
