It seems I have soled this problem on my own computer.It is a Acer Travelmate 3274.I've being geting along with this problem for almost 1 year.I found it's all because there is conflict between my cdrom and the disk.when I executed "ll /dev/ ",I saw [code] lrwxrwxrwx 1 root root 3 2009-10-21 13:28 cdrw -> sr0 lrwxrwxrwx 1 root root 3 2009-10-21 13:28 dvd -> sr0 lrwxrwxrwx 1 root root 3 2009-10-21 13:28 dvdrw -> sr0 lrwxrwxrwx 1 root root 3 2009-10-21 13:28 cdrom -> sr0 [/code] so I just [code]rm /dev/sr0[/code] And my computer work well for almost 6 hours until now. Sorry for my poor english.Hope some one can understand what I've said. this is my e-mail:melancholy.kni...@gmail.com
