This bug is awaiting verification that the linux-oem- 6.5/6.5. 0-1004. 4 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- jammy-linux- oem-6.5' to 'verification- done-jammy- linux-oem- 6.5'. If the problem still exists, change the tag 'verification- needed- jammy-linux- oem-6.5' to 'verification- failed- jammy-linux- oem-6.5' .
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!
