My system is an Asus G50vt-X5 with a GSA-T50L optical drive (dvd rw).
When I try booting off the Fedora Live CD, I get this error during the process repeated a number of times before it continues. Most often I can boot all the way into the distro and work for a little while before I can't open any more programs. At this point the drive would stay spinning and nothing you do can open it or stop the spinning but turning the computer fully off and then back on. The drive works perfectly within Windows Vista and Windows 7.
I came across this thread:
https://bugs.launchpad.net/ubuntu/+s...ls/+bug/307477 which seemed to help tremendously. I went to the Asus website and installed an updated firmware. The live cd now allows me to boot and has been working properly. I still get the buffer error upon boot though.
Searching around further on Google, it seems that there is quite a few people having this problem with all different laptop manufacters, different distros, and all SATA optical drives. This problem seems to have popped up with newer kernel versions, being that a lot of people didn't have the problem before trying to upgrade. Most of the answers are the standard reburn the cd/dvd/whatever and try again. This unfortunately doesn't help as the disks work fine on other non sata drives.
Anybody have a clue what is going on here? Is there any sort of kernel option that allows better use of SATA drives?
