This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1727290

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

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

Is this only happening on the linux-azure kernel, or also with the generic kernel?

Also, do you know if this issue is a regression? If it is, we can bisect down the commit that introduced the bug.

It might be worth seeing if this is already fixed in mainline as well:

Hey Joe,

It's only spotted on the linux-azure kernel.

As we haven't test this all the way from 4.11.0-1006.6 to this cycle, I think maybe it's better to not call it a regression for this kernel.

I will test the mainline kernel once I got access to it.
Thanks

This issue can be reproduced on 4.11.0-1014.13 azure kernel.

Verified with 4.14-rc6 (4.14.0-041400rc6-generic), this issue does not exist.

Verified with the oldest version in the archive: 4.11.0-1009-azure
This issue still exist.

I think we only test those kernels older than 4.11.0-1009-azure in proposed pocket.

very old bug, with no action on it, marking bug as incomplete and will
close in 5 days if no update.

This issue still exist
4.15.0-1023.24-azure

This is affecting azure linux-azure cosmic 4.18.0-1019.19.

As we have updated the upstream git repo, this bug will needs to be revisited.

Passed with D-Azure 5.0

Hi Sam,

I believe this test is passing on our supported bare metal kernels as well as their linux-azure counterparts now.

These are the kernels whose results I looked at on the Jenkins server:

* 5.3.0-21.22
* 5.0.0-34.36
* 4.15.0-68.77
* 4.4.0-167.196
* 5.3.0-1006.6 (azure)
* 5.0.0-1024.25 (azure)
* 5.0.0-1024.25~18.04.1 (azure)
* 4.15.0-1062.67 (azure)

All of these kernels are in -proposed, but I think these tests have been passing on previous kernels as well.

marking fix released On 8/21/2019, the git repo was updated for this test. It properly uses the upstream version now. Since then this test has been passing on Azure.
