This bug is awaiting verification that the linux-azure/6.2.0-1009.9 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-lunar' to 'verification-done-lunar'. If the problem still exists, change the tag 'verification-needed-lunar' to 'verification-failed-lunar'.

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 for documentation how to enable and use -proposed. Thank you!
