Linux kernel in Ubuntu doesn't provide mmc-modules udeb.

[Shih-Yuan Lee]

[Impact]

 * The users can not use netboot.iso to install Ubuntu on eMMC storage.

[Test Case]

 * Download netboot.iso of trusty/utopic/vivid from http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-amd64/current/images/
 * Use netboot.iso to burn an installation CD/DVD or make an installation USB stick.
 * Use this installation media on a platform with eMMC storage to install Ubuntu system.

[Regression Potential]

 * None

[Other Info]

 * None

Linux kernel in Ubuntu doesn't provide mmc-modules udeb like https://packages.debian.org/unstable/mmc-modules-4.2.0-1-amd64-di in Debian.
So it makes us unable to install the Ubuntu system into eMMC storage via netboot, aka http://archive.ubuntu.com/ubuntu/dists/wily/main/installer-amd64/current/images/netboot/.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This issue also needs to update the debian-installer in http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-amd64/current/images/ or we can not verify it.

[Shih-Yuan Lee (fourdollars)]

Could you help to update the debian-installer netboot images, such as http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-amd64/current/images/vivid-netboot/mini.iso and http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-amd64/current/images/netboot/mini.iso so I can verify this issue?

We need to get this kernel released due to bug #1508510. Tagging as verified.

I didn't use any preseed config. I just download the mini.iso and make an installation USB stick by it.
Then I plug the USB stick into a laptop that only has an eMMC system storage inside to do the installation test manually.
During the installation, I will connect to Internet to download other udeb packages and this is the usual usage for mini.iso.

http://archive.ubuntu.com/ubuntu/dists/wily-proposed/main/installer-amd64/current/images/netboot/mini.iso works and /proc/version_signature shows "Ubuntu 4.2.0-16.19-generic 4.2.3".

http://archive.ubuntu.com/ubuntu/dists/vivid-proposed/main/installer-amd64/current/images/netboot/mini.iso doesn't work and /proc/version_signature shows "Ubuntu 3.19.0-30.33-generic 3.19.8-ckt6".

http://archive.ubuntu.com/ubuntu/dists/trusty-proposed/main/installer-amd64/current/images/utopic-netboot/mini.iso doesn't work and /proc/version_signature shows "Ubuntu 3.16.0-52.71~14.04.1-generic 3.16.7-ckt8".

It is expected that "Ubuntu 3.13.0-67.110-generic 3.13.11-ckt27", "Ubuntu 3.19.0-32.37~14.04.1-generic 3.19.8-ckt7" and "Ubuntu 4.2.0-16.19-generic 4.2.3" work and "Ubuntu 3.19.0-30.33-generic 3.19.8-ckt6" doesn't work.

It is not expected that "Ubuntu 3.16.0-52.71~14.04.1-generic 3.16.7-ckt8" doesn't work but we don't maintain utopic now so it is probably OK.

The only problem left now is that http://archive.ubuntu.com/ubuntu/dists/vivid-proposed/main/installer-amd64/current/images/netboot/mini.iso is not up to date.
