[Kernel-packages] [Bug 2033025] Re: Fix numerous AER related issues
This bug is awaiting verification that the linux- nvidia-6.2/6.2.0-1011.11 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-6.2' to 'verification-done-jammy-linux-nvidia-6.2'. If the problem still exists, change the tag 'verification-needed-jammy-linux-nvidia-6.2' to 'verification-failed-jammy-linux-nvidia-6.2'. 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 bug is awaiting verification that the linux/6.2.0-34.34 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-lunar-linux' to 'verification-done-lunar-linux'. If the problem still exists, change the tag 'verification-needed-lunar- linux' to 'verification-failed-lunar-linux'. 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.
