This bug is awaiting verification that the linux-azure/6.5.0-1013.13 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-mantic-linux-azure' to 'verification-done- mantic-linux-azure'. If the problem still exists, change the tag 'verification-needed-mantic-linux-azure' to 'verification-failed-mantic- linux-azure'.
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.
