Bug Description


Currently the DKMS package fails to install in supported custom kernels that are based on 4.11 or 4.13. That includes the current 4.11 hwe-edge and the upcoming 4.13 hwe-edge kernels and some of the custom and cloud kernels as well.

[Test Case]

Install the DKMS package with the 4.13 hwe-edge kernel from -proposed. The package installation should proceed without any errors.

[Regression Potential]

Although new patches were added, the regression risk is very low since the new changes are conditionally compiled based on the kernel version.

Besides that the new package was tested with the following kernels in an amd64 environment:

- linux-generic 4.4
- linux-hwe 4.10
- linux-hwe-edge 4.11
- linux-hwe-edge 4.13 (from xenial-proposed)
- linux-azure 4.11
- linux-azure-edge 4.13 (which is in process of getting promoted to

Hello Seth, or anyone else affected,

Accepted rt-tests into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/rt-tests/0.93-1ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-xenial to verification-done-xenial. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-xenial. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I have tested the version 0.93-1ubuntu2 and the DKMS package successfully builds and loads on kernels 4.13, which was the issue reported in this bug.

I also have run the ADT tests for the following kernels to ensure there's no regressions:

- linux-generic 4.4
- linux-hwe 4.10
- linux-hwe-edge 4.11
- linux-hwe-edge 4.13
- linux-azure 4.11
