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