This bug is awaiting verification that the linux-lowlatency-
hwe-6.11/6.11.0-1007.7~24.04.1 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-noble-linux-
lowlatency-hwe-6.11' to 'verification-done-noble-linux-lowlatency-
hwe-6.11'. If the problem still exists, change the tag 'verification-
needed-noble-linux-lowlatency-hwe-6.11' to 'verification-failed-noble-
linux-lowlatency-hwe-6.11'.


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!
