initrd not being loaded on Windows Azure

[Ben Howard]

The hv_storesc driver has been removed from the initramfs drivers. This prevents 12.10 from booting on Windows Azure.

Ok this module seems to be in the linux-image-generic binary package as expected:

    -rw-r--r-- root/root 25008 2012-10-08 15:19 ./lib/modules/3.5.0-18-generic/kernel/drivers/scsi/hv_storvsc.ko

The initramfs-tools scripting to include these seems to still be present:

        virtual)
                # Hyper-V
                for x in hv_vmbus hv_utils hv_netvsc hv_mouse hv_storvsc; do
                        manual_add_modules "${x}"
                done

And looking at a current quantal install they seem to be in the initrd:

    ./lib/modules/3.5.0-18-generic/kernel/drivers/scsi/hv_storvsc.ko
