Comment 45 for bug 1386534

Due to your careful question, it turned out, that I have made very serious error!

When installing your "Utopic test kernel with commit b47f210 reverted"

        I did not install the linux-image-extra...

I tried to check whether I did same kind of error earlier.

In case of 3.13.0-36-generic, 3.13.0-36-generic and 3.16.0-28-generic, and in general, if the installation source was an Ubuntu release, then the extra was there always.

In case of kernel-PPA, following the https://wiki.ubuntu.com/Kernel/MainlineBuilds tips ( comment here: #30), I installed the headers as well, while I did NOT installed the kernel extra, since there is no such separated stuff. I tested quite a lot of kernels.

But, do I see correctly, that a size of greater than 50MB of kernel binary package means, that that package contains the extras as well? I see, when there is a separate extra package, then the normal and extra package together is slighly larger than the single "over 50MB" kernel binary package, this is why I think that this kind of single package contains the extras as well.

Then I got 4 different kernels upto diverse commits, but since they are gone from the URL you gave me, I can not RETEST them, ... while I am suspicious that I did not install the extras, but may happen that I installed on the base of "why not if it is there", simply I do not remember.

Now in case of the latest kernel, which is already an "Utopic test kernel with commit b47f210 reverted", I am sure, that I did NOT install extras.

However this kernel without the extras, --- due to it's revision number collision with the similar kernel of the normal Ubuntu release, --- is sensitive to whether the packages of the normal Ubuntu kernels are there or not.

In my #42 comment: the extras of the normal release kerlen of the same version number was there, while the extras you provided were NOT installed, and in this case I get the usual error.

But, if I remove any trace of the normal release kernel, and then I install your kernel with extras, then IT WORKS, ... actually I write this comment using your latest kerenel provided me!

I try to prevent this kernel from updating by the automatic updating system of Ubuntu.

Is installing linux-image-### and linux-image-extra-### enough to get rid of the other kernel with same version number, or what I have to do to make a clean install of the kernels you gave me?

In short: 3.13.0-36-generic works, 3.13.0-37-generic has the issue, official 3.16.0-28-generic also has the issue, but YOUR 3.16.0-28-generic WORKS.

I really excuse myself for my big error and WASTING YOUR TIME, and naturally I am ready to repeat former tests, if you could provide those packages again.

This week I prepared to formulate my thanks that regardless of we know each other you give your time and knowledge, ... and jut in this week I had to discover my error vasting resources. I advocate the free softwares approximately since two and half decades, as a university staff, so in theory I understand the importance and the meaning of this global movement, ... but it is very touching to have such an abstract and at the same time personal experinece, that someone from the mankind whom I even don't know on which continent is resident, helps.
