This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --------------enig6C091EF6BFC0F5198B4C9B42 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello, I'm experimenting with MS-Hyper-V and saw that as soon as hv_storvsc.ko is loaded, an IDE hdd attaches as 'da' _and_ 'ada' (the former seems to be called =E2=80=9CFastIDE=E2=80=9D on =E2=80=9Csynthetic storage driver=E2= =80=9D and gains efficiency for HDD workloads). There's the hv_pci_ata_disengage.ko pseudo driver, but that also makes IDE cdrom unavailable =E2=80=93 same as disabling ata/atapci! Can't reall= y get the idea of that module=E2=80=A6 I'd prefere to disable 'ada' only (leaving cdrom via atapci->ATA_CAM->cd)= =2E But I can't find the place where =E2=80=9Cdevice ada=E2=80=9D gets define= d for kernel conf. =E2=80=9Cdevice ata=E2=80=9D is in GENERIC, along with da, sa, scbu= s etc., but no 'ada' ?!?. No trace of 'ada' in DEFAULTS either!?! Is there something like hint.ada.disable=3D1 ? Can I use =E2=80=9Cnodevice ada=E2=80=9C to exclude it from my custom ker= nel?
