Bug#749016: linux-image-3.14-1-amd64: initrd generated under 3.14-1 v3.14.4-1 does not load sd_mod, boot fails

[Zack Weinberg <zackw@panix.com>]

I apologize for the delay in getting back to you.

With initramfs-tools 0.118,  linux-image 3.16.7-2, and udev 215-5+b1,
I do not need to put sd_mod in /etc/initramfs-tools/modules for the
initramfs to detect and mount the root filesystem.

Unfortunately, only a few days before you sent this query I upgraded
the motherboard on the affected computer, so I can't say for certain
that the problem is *fixed*, only that it does not affect this
computer anymore.
