Bug Description

upstream commit 6dfb54049f9a99b24fe5d5cd2d3af19eadc8f31f contains an enhancement to xmon to allow listing running tasks. This is vital to debugging efforts, and so needs to be added to as many release streams as possible, as soon as possible.

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!

There seems to be several kernels in -proposed for xenial. I ran on 4.8.0-28-generic and 4.4.0-49-generic.

The "P" command is present and works as desired.

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.
