This bug is awaiting verification that the linux-nvidia- tegra/6.8.0-1001.1 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-nvidia-tegra' to 'verification-done-noble-linux-nvidia-tegra'. If the problem still exists, change the tag 'verification-needed-noble-linux-nvidia-tegra' to 'verification-failed-noble-linux-nvidia-tegra'.
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.

[Test Case] run suspend/resume test case for over 100 times, the wifi still works. [Where problems could occur] This commit comes from mailine kernel, and it doesn't change existing driver except loading firmware a couple of more times if there is an error. In theory this will not introduce regression.
