Bug Description

The Infiniband driver (kernel module) needed for Azure A8/A9, H-series, and NC24/NV24 instances is different than the typical upstream Infiniband driver. Also, the WALA agent must be customized to ensure that the host driver for IB and the guest driver for IB match.

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-xenial' to 'verification-done-xenial'.

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!

We'll take a look at this right away. Thanks for the quick integration.

The verification of the Stable Release Update for linux-lts-xenial has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
