hi,

today i bought a LG CH10LS20 blue ray reader/cd/dvd writer combo. after replacing the drive and reboot i exerience the following.

the pc restarts and become unresponsible for quite some time 1-2 mins. then it goes on with booting and i end up in kde as usual. the new drive isnt recognized by the system and also im unable to open the tray. speak the drive doesnt respond to anything. so my first thought was, i got a faulty drive and took it back to the vendor.
he plugged the drive onto a win7 pc and ofcourse the drive works well (he played a blue ray, copied some files from a cd and last burned a dvd while i watched).so i can be sure the drive is 100% functional now.

my system is : ubuntu 10.10 with latest updates amd64
the mainboard is : ASUSTeK Computer INC. M4A78 PRO
the onboard sata controller is: SATA controller: ATI Technologies Inc SB700/SB800 SATA

dmesg output after booting (just the impotant things) looks like :




[ 2.650028] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)

i also tried the sata interface with ahci and ide with always the same result.

so maybe one fellow ubuntu user can tell me whats going wrong here since allmighty google didnt bring up any useful information to my problem.

thanks in advance for reading/giving a solution :)

Hello!

I have exactly the same problem, my configuration:

Ubuntu 10.10 amd64
Asus M4A785G HTPC
LG CH10LS2 Combo

Windows 7 have no problem, it boot and play dvd/bluray correctly. When i try to install ubuntu whit the livecd i recive this error: "unable to find medium containing a live file system".
I use to install ubuntu using a usb key, the system will install but at the first reboot it takes 3/4 minutes to boot, and the dvd isnt recognized and i can't open the tray... Exactly same problem...

I update bios of the mainboard, i try to search a firmware update for the dvd but there is nothing.

I home someone can help us :-(

Thanks a lot in advance!!!!!! :) :)
