This bug is awaiting verification that the linux- nvidia-6.5/6.5.0-1014.14 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-6.5' to 'verification-done-jammy-linux-nvidia-6.5'. If the problem still exists, change the tag 'verification-needed-jammy-linux-nvidia-6.5' to 'verification-failed-jammy-linux-nvidia-6.5'.
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.

On my testing machine with 16GB of memory (transparent hugepage is turned off by default, and movablecore=12G is configured) The following is a comparative test data of watermark_min no patch add patch ZONE_DMA 1 8 ZONE_DMA32 151 709 ZONE_NORMAL 233 1113 ZONE_MOVABLE 1434 128 min_free_kbytes 7288 7326 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-nvidia-6.5/+bug/2055712/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
