This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1591644

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I can use command "apport-collect 1591644" only on Ubuntu 15.10. Ubuntu 16.04 has no internet from my YOTA LU150 modem.

[Pavel (metalarchus)]

Maybe it does not work on 16.04 because of this:

Pavel, in order to allow additional upstream developers to examine the issue, at your earliest convenience, could you please test the latest upstream kernel available from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D ? Please keep in mind the following:
1) The one to test is at the very top line at the top of the page (not the daily folder).
2) The release names are irrelevant.
3) The folder time stamps aren't indicative of when the kernel actually was released upstream.
4) Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds .

If testing on your main install would be inconvenient, one may:
1) Install Ubuntu to a different partition and then test this there.
2) Backup, or clone the primary install.

If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ

Where X, and Y are the first two numbers of the kernel version, and Z is the release candidate number if it exists.

If the mainline kernel does not fix the issue, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ

Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream.

Also, you don't need to apport-collect further unless specifically requested to do so.

Once testing of the latest upstream kernel is complete, please mark this report Status Confirmed. Please let us know your results.

Thank you for your understanding.

[Pavel (metalarchus)]

On the kernel 4.4.14 (http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/linux-image-4.4.14-040414-generic_4.4.14-040414.201606241434_amd64.deb) and later all work. I had tried to use the kernel 4.17 RC5 and the modem also worked on it.

What i did:
1) I downloaded this files: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/linux-headers-4.4.14-040414-generic_4.4.14-040414.201606241434_amd64.deb http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/linux-headers-4.4.14-040414_4.4.14-040414.201606241434_all.deb and http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.4.14-xenial/linux-image-4.4.14-040414-generic_4.4.14-040414.201606241434_amd64.deb
2) I installed lubuntu 16.04
3) cd /path/to/the/downloaded/files
4) sudo dpkg -i *.deb

[penalvch (penalvch)]

Pavel, the next step is to fully reverse commit bisect from kernel 4.2 to 4.4.14 in order to identify the last bad commit, followed immediately by the first good one. Once this good commit has been identified, it may be reviewed for backporting. Could you please do this following https://wiki.ubuntu.com/Kernel/KernelBisection#How_do_I_reverse_bisect_the_upstream_kernel.3F ?

Please note, finding adjacent kernel versions is not fully commit bisecting.

Also, the kernel release names are irrelevant for the purposes of bisecting.

After the fix commit (not kernel version) has been identified, then please mark this report Status Confirmed.

Thank you for your help.
