K.Y.: Youre _theory_ ( about "can solve the issue on hand using modprobe
rules") is wrong for:

As I said, if the ata_piix driver is a loadable module, we can solve the issue with modprobe rules. If it is not a loadable module we cannot obviously solve the problem with modprobe rules
and we will need the ata patch.

Nothing new: -- "the ata patch" is need, if we want worked 100% / 100% Linux on Hyper-V
-- "solve the problem with modprobe rules" very often not worked solution ( i.e. if the ata_piix driver . . . )

Total:

{
cd006086fa5d ata_piix: defer disks to the Hyper-V drivers by default

and its prerequisite

db63a4c8115a libata: add a host flag to ignore detected ATA devices
}
need be backported from

3.5

to

3.4.latest
3.3.latest
3.2.latest

P.S.

As I said, if the ata_piix driver is a loadable module, we can solve the issue with modprobe rules.

We can test Youre theory:

. . .

with use only "modprobe rules" prepare binary patch ( .xDelta) for <Linux_Distib_ZZZZ_Kernel_3.2_>

. . .

Goal: work in Hyper-V guest as ( ( Linux_Distib_ZZZZ_Kernel_3.1_.iso ) + worked mouse ) ) in LiveCD and after install
