Interesting. It seems many SATA controllers have an IDE compatibility
mode (BIOS setable):
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:
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:
Another idea is to try changing the SATA port the CDROM is plugged into.
