Comment 9 for bug 929545

Ok. I have attempted to add hyper-v detection to the ata_piix driver. This basically defers handling to hyper-v by default if the hypervisor is detected. I have also added an override to allow this to be suppressed from the command line. Could someone with a hyper-v based cloud test the kernels below and report whether they work here. Could you please include a dmesg of a successful boot so I can confirm the detection has recorded itself correctly. It would also be helpful to get a boot with ata_piix.prefer_ms_hyperv=0, again a dmesg would be useful. Kernels are at the URL below:

Kernels should be synced shortly. Thanks.
