My DVD device goes wrong when grub2 is running, til I shut down my laptop.

[hotwave]

I think it's a bug.

My laptop is a Lenovo Ideapad Y710 - 2GB Ram - 250 GB HDD - OptiArc DVD-RW - 
Intel 4965agn wireless - Broadcom NetLink BCM5906M Fast Ethernet PCI Express - 
Lenovo EasyCam - Intel HD Audio (ALC888).

It was preinstalled windows vista . Early, I replaced vista by win xp . Before 
long , I try to install ubuntu 8.04 beside windows xp , and I can switch either 
OS I want in grub when I switch on my laptop . Till then ,everything runs well.

But one day , I update grub to grub2 . After reboot , when grub2 start , the 
LED of DVD device kept light til I shut down my laptop or eject DVD device( 
that's odd) . Even worse that neither winxp nor linux could detect my DVD 
device whenever ejected or not .

This problem harass me more than one year , and no update fix it.

I only know little about developing , but I want to do everything I could to 
help developers to fix this bug.
