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.

Install AMD W7500/W7600/W7700 graphics 2. Install latest firmware with dcn_3_2_0_dmcub.bin for Navi31 and 32 and dcn_3_2_1_dmcub.bin for Navi33. 3. Running fwts s3 stress test to check if system hangs [Where problems could occur] Improve the error handling when suspend and add the fallback mechanism in MES engine.
