With 2.6.31.2 from kernel.org I got the following output with "lspci -v":
00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] (prog-if 80 [Master])
Subsystem: Qumranet, Inc. Device 1100
Flags: bus master, medium devsel, latency 0
[virtual] Memory at 000001f0 (32-bit, non-prefetchable) [disabled] [size=8]
[virtual] Memory at 000003f0 (type 3, non-prefetchable) [disabled] [size=1]
[virtual] Memory at 00000170 (32-bit, non-prefetchable) [disabled] [size=8]
[virtual] Memory at 00000370 (type 3, non-prefetchable) [disabled] [size=1]
I/O ports at c000 [size=16]
Kernel driver in use: ata_piix
Kernel modules: ata_generic, ata_piix, ide-pci-generic, piix
whereas with linux-image-2.6.26-2-amd64 stock kernel installed from a
binary image from Debian repositories I got the following output with
"lspci -v":
00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] (prog-if 80 [Master])
Subsystem: Qumranet, Inc. Device 1100
Flags: bus master, medium devsel, latency 0
[virtual] Memory at 000001f0 (32-bit, non-prefetchable) [disabled] [size=8]
[virtual] Memory at 000003f0 (type 3, non-prefetchable) [disabled] [size=1]
[virtual] Memory at 00000170 (32-bit, non-prefetchable) [disabled] [size=8]
[virtual] Memory at 00000370 (type 3, non-prefetchable) [disabled] [size=1]
I/O ports at c000 [size=16]
Kernel driver in use: PIIX_IDE
Kernel modules: ata_generic, ide-pci-generic, piix
According to I see, are different the modules that each kernel has and
uses. As I said in previous post, I found that to use libara these [1] are
the required parameters in the config file, and although some of them are
configured like modules, they are exactly the same for both kernels so I
suppose that the difference must happen on the other hand.
Thanks for your reply.

Daniel
