I tried the GRUB_CMDLINE_LINUX="libata.force=5:nohrst" in my /etc/default/grub file and rebuilding grub with update-grub2, but saw no change. dmesg still reported the exact same softreset issues. This was with me putting a disc in the drive at boot and having tried under IDE, ACHI and RAID. Still nothing. Wish this was a solution for my issue.
It's frustrating because this CH20L drive works perfectly in Windows 7 64 bit for burning DVD/CD, blu-ray read, etc., just not in 64 bit Linux. I've tried Ubuntu, Fedora, Mint, Mandriva, Sabayon, etc. Nothing. No power to the drive even. Once Ubuntu boots fully, the drive has no power and the button does not eject the tray. It doesn't seem that it's being addressed upstream at all either. I keep trying newer and newer kernel builds and the issue persists. No issues with 32 bit Linux though. Drive works great in 32 bit Ubuntu 10.10 as well as other distros.
