Losing port aggregate with 802.3ad port-channel/bonding aggregation on reboot

[Celia Wang]

The exactly the same behavior is observed when upgrade kernel to 4.15.0-123-generic.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834322

If we do 'ip link set dev bond2 down' and 'ip link set dev bond2 up', the port with the mismatched ID appears to renegotiate with the port-channel and becomes aggregated.

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 1904529

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 ran "apport-collect 1904529" but choosed "V" to view the reports then "C" cancelled sending.
The second time I was trying to run this cmd again to send reports, I've got the error of "You are not the reporter or subscriber of this problem report, or the report is a duplicate or already closed."

Is there another way that I can gather and send reports?

So it's a regression on 4.15.0-123? What was the last working version?

[Diko Parvanov (dparv)]

It's not clear what was the previous most recent kernel that the machine was running before the upgrade and reboot, however previous installed kernel on the machines were:

2019
Jun 24 4.15.0-54
Jul 2 4.15.0-55
Aug 6 4.15.0-58

2020
Jun 23 4.15.0-109
Jul 9 4.15.0-112
Oct 21 4.15.0-123 --> last kernel install

possibly previous working kernel was 4.15.0-112, but might have been any of the previous ones.

[Kai-Heng Feng (kaihengfeng)]

It needs to be exact to find where the regression happened...

Hello Xiyue Wang,

Could you please try the latest bionic kernel from -proposed? The version would be linux-generic 4.15.0.128.115.

Following are instructions on how to enable proposed: https://wiki.ubuntu.com/Testing/EnableProposed

Thank you.
