is there a setting in your bios that mentions something like 'combined mode' or 'legacy' mode relating to sata ? If so, disable it. There is nothing in my BIOS that relates to SATA. On further investigation, the hard drive and DVD drive might not be SATA, but ATA instead. The drive is loaded as SCSI, and the DVD drive needs to be loaded as such if one wants DMA. There's a SATA controller in the laptop, but the harddrive is ATA from what I've seen. Perhaps they've put in a SATA-ATA converter? Sorry, but the drive's not easily user accessible. can you attach dmesg output ? If it's ATA, then hdc is the correct node for it. duplicate of bug 163418 There is currently 'experimental' atapi through SATA support and SATA dvd support. It works well for me. I have DMA on my DVDRW. Created attachment 127904 [details]
Default boot, DVD as hdc and no DMA
Attached the dmesg output from the default boot.
The drive is available as /dev/hdc, and does not
and can not have DMA enabled.
A new kernel update has been released (Version: 2.6.18-1.2200.fc5) based upon a new upstream kernel release. Please retest against this new kernel, as a large number of patches go into each upstream release, possibly including changes that may address this problem. This bug has been placed in NEEDINFO state. Due to the large volume of inactive bugs in bugzilla, if this bug is still in this state in two weeks time, it will be closed. Should this bug still be relevant after this period, the reporter can reopen the bug at any time. Any other users on the Cc: list of this bug can request that the bug be reopened by adding a comment to the bug. In the last few updates, some users upgrading from FC4->FC5 have reported that installing a kernel update has left their systems unbootable.

If this bug is a problem preventing you from installing the release this version is filed against, please see bug 169613. If this bug has been fixed, but you are now experiencing a different problem, please file a separate bug for the new problem. Thank you. (this is a mass-close to kernel bugs in NEEDINFO state) As indicated previously there has been no update on the progress of this bug therefore I am closing it as INSUFFICIENT_DATA.
