Excellent work on finding more information about the cause and a

This does indeed appear to be a serious issue, but it is unfortunately
not a charm issue.
It appears to me to be an issue with the mlx5 driver in the kernel which
is visible in this specific environment for yet to be uncovered reasons.

Note that for the log references where the autopkgtest runs using a 6.1

those locally and the problem goes away when upgrading to a mainline

@cjwatson thanks alot for chiming in on the issue. I added Launchpad,
because I was unsure what part Launchpad has in the massaging of
