It seems many SATA controllers have an IDE compatibility mode (BIOS setable): http://cateee.net/lkddb/web-lkddb/ATA_SFF.html http://cateee.net/lkddb/web-lkddb/ATA_PIIX.html In anycase, Victor's controller is using the modern AHCI mode: : 00:1f.2 SATA controller: Intel Corporation 82801IR/IO/IH (ICH9R/DO/DH) 6 : port SATA Controller [AHCI mode] (rev 02) (prog-if 01 [AHCI 1.0]) : Subsystem: Dell 82801IR/IO/IH (ICH9R/DO/DH) 6 port SATA : Controller [AHCI mode] If CONFIG_ATA_BMDMA=Y works, I'd still say there is a bug or misinformation out there somewhere. In any case, he said it was working under 4.4.2, but broke in 4.4.4. Assuming "make oldconfig" was used to import/convert the original 4.4.2 configuration to the newer kernel: http://lists.kernelnewbies.org/pipermail/kernelnewbies/2011-August/003085.html it is possible Victor is seeing a kernel bug. Perhaps a test of 4.4.3 is in order. I do not see anything related (e.g., SATA, 82801IR) in the changelogs of 4.4.3 and 4.4.4: https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.4.3 https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.4.4 Another idea is to try changing the SATA port the CDROM is plugged into.
