(Get the code!)
@Philip:
I retried with the 32 bit version, it failed also. It seems for the first tests with the new pc i accidentally fetched not Ubuntu 10.10 32 bit. (I have several live linux versions here. Maybe I fetched one which uses also ata_generic like fedora. I only used the commandline for the first tests.) I'm sorry for the wrong info in the first post.
In the bios i tried all three settings IDE, RAID and AHCI, nothing changed (Ubuntu was also loading the kernel module ahci with all settings.)
Another optical drive a Plextor PX-L890SA was connected to the same controller all the time. It worked all the time (with every setting) perfectly. So it seems to be just the LG drive that fails when it gets the hard reset (i have not other sata controller at hand to test it, the other one in the system has only an internal pata port).
I would guess it is a bug in the drives firmware (that doesn't show up in Windows 7) or (with less probability) it is bug in the ahci kernel module.
Does someone know if ata_generic is hard ressetting the link?
