      What were you trying to do that didn't work?

      While testing a CVE with the RT-Kernel, I encountered an issue where the NVMe-FC connections were failing to establish. Below is from the console:

       

      [   24.459197] nvme nvme5: Connect command failed, errno: -18 
      [   24.459199] nvme nvme5: qid 0: secure concatenation is not supported 
      [   24.459359] nvme nvme5: NVME-FC{4}: create_assoc failed, assoc_id 200 ret 401 

      If simply provisioning the system and installing the rt-kernel, no issue is observed. I only hit the problem by running this task:

       

      https://gitlab.cee.redhat.com/kernel-qe/kernel/-/archive/master/kernel-master.tar.gz#rt-tests/env_test

      I can also manually reproduce by running these commands:

       

      # dnf install tuned tuned-profiles-realtime
      # tuned-adm profile realtime
      # rhts-reboot

      Below is one job where the problem was observed:
