This bug is awaiting verification that the linux-azure- nvidia-6.14/6.14.0-1004.4~24.04.1 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- azure-nvidia-6.14' to 'verification-done-noble-linux-azure-nvidia-6.14'. If the problem still exists, change the tag 'verification-needed-noble- linux-azure-nvidia-6.14' to 'verification-failed-noble-linux-azure- nvidia-6.14'.
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.

This can lead to odd side effects as the count does not represent the actual state of the hardware. Backport fix to 6.14-HWE.
