[Bug 2077384] Re: rtw89: Support hardware rfkill

This bug is awaiting verification that the linux-
realtime-6.11/6.11.0-1003.3~24.04.2 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-
realtime-6.11' to 'verification-done-noble-linux-realtime-6.11'. If the
problem still exists, change the tag 'verification-needed-noble-linux-
realtime-6.11' to 'verification-failed-noble-linux-realtime-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!
