Public bug reported: [Impact] The GPU Direct over Infiniband feature of NVIDIA GPUs no longer works on jammy/hwe kernels that have migrated to 6.5 *except* for the -nvidia kernel, which pulled in support via bug 2049537.
We have carried this patch since 5.4 (see bug 1923104). We do not plan to carry this patch into 6.8 or later - we are working on a deprecation post for that to give users some time to migrate.
