This bug is awaiting verification that the linux-nvidia-
tegra-5.15/5.15.0-1027.27~20.04.1 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-focal-linux-
nvidia-tegra-5.15' to 'verification-done-focal-linux-nvidia-tegra-5.15'.
If the problem still exists, change the tag 'verification-needed-focal-
linux-nvidia-tegra-5.15' to 'verification-failed-focal-linux-nvidia-
tegra-5.15'.


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!
