I also have the same problem. My burner is a Plextor 810SA with the latest firmware. I have an Asus Striker Extreme motherboard and running 4GB ram. I've tried falling back to earlier kernel's and the problem still exists. I was wondering if my HDD was failing. All 3 of my HDD are SATA as well as my burner. I'll try some of the "fixes" here to see if they will "correct" the problem. It's reassuring that I'm not the only one with problems.
