From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.10) Gecko/20071126 Fedora/2.0.0.10-1.fc8 Firefox/2.0.0.10 Description of problem: During boot there are error messages (before graphical screen pops up): ata6: failed to recover some devices, retrying in 5 secs ata6: port is slow to respond, please be patient (Status 0x80) ata6: COMRESET failed (errno=-16) and the boot is extremely slow. After boot the DVD-RW device does not work, all other SATA devices (hard disks) work correctly. Version-Release number of selected component (if applicable): kernel-2.6.23.1-42, kernel-2.6.23.8-63 How reproducible: Always Steps to Reproduce: 1. Boot with Fedora 8 2. 3. Actual Results: Expected Results: Additional info: The motherboard is Gigabyte GA-965P-DQ6 (1.0) with ICH8R southbridge, and SATA device handling is set to "RAID mode" in BIOS. Ubuntu 7.10 and OpenSuse 10.3 work correctly with the same hardware configuration (with 2.6.22 kernel). Earlier Fedora 7 worked as well without problems. It doesn't matter if you your standard or PAE kernel.

Dear Support Team! Thanks for your incredible support. Without that it wouldn't have come true. As a average user, I'm not sure if I answered all of your very detailed and sophisticated questions. I tried. A big thank to you all. Other Fedora Users! The bug is away with the new 2.6.24 kernel (probably the problem was in the new libata part). So the SATA DVD-RWs are working again. Update your kernel if you have the same problem.
