Found out why it works in the latest stable/5.15.y kernel, and identified the cherry-pick required.
Commit 3feac2b5529335dff4f91d3e97b006a7096d63ec in stable/5.15.y is required to be cherry-picked to the 5.15 jammy kernel to fix this. I will work on getting this in to the jammy 5.15 kernel. ** Changed in: linux (Ubuntu) Status: Triaged => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2076576 Title: 5.15.0-118: NFS causes suspend to fail To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2076576/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
