NVIDIA internal test shows kernel warning during suspend/resume

[Noah Wager]

NVIDIA has found that a new kernel warning is produced during suspend/resume. This has been determined to be caused by the new upstream stable patch "genirq: Make handle_enforce_irqctx() unconditionally available" which exposes an old bug in NVIDIA's code. We can revert this upstream patch to temporarily fix the warning, and a true fix will be shipped in the future.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is awaiting verification that the linux-nvidia-tegra-igx/5.15.0-1026.26 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-jammy-linux-nvidia-tegra-igx' to 'verification-done-jammy-linux-nvidia-tegra-igx'. If the problem still exists, change the tag 'verification-needed-jammy-linux-nvidia-tegra-igx' to 'verification-failed-jammy-linux-nvidia-tegra-igx'.

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!
