Description of problem: Kernel args "iommu=on iommu=ppt" not propagating after reboot of compute node Version-Release number of selected component (if applicable): How reproducible: every time Steps to Reproduce: 1. Include iommu args in grub cfg: /boot/grub2/grub.cfg (see additional info) 2. Following compute node creation, reboot the node 3. Check the command line output Actual results: "iommu=on iommu=ppt" not present in command output Expected results: "iommu=on iommu=ppt" should be present in command output Additional info: 2022-06-29 16:42:24.771672 | 5254009b-c4f4-9d47-3a71-000000001541 | TASK | Reboot after kernel args update 2022-06-29 16:42:24.777958 | 5254009b-c4f4-9d47-3a71-000000001567 | OK | Reboot debug message | compute-0 | result={ "changed": false, "msg": "Going to reboot the node after applying kernel args..." } 2022-06-29 16:42:24.780674 | 5254009b-c4f4-9d47-3a71-000000001567 | TIMING | tripleo_kernel : Reboot debug message | compute-0 | 0:01:07.407393 | 0.05s 2022-06-29 16:42:24.800832 | 5254009b-c4f4-9d47-3a71-000000001568 | TASK | Reboot after kernel args update 2022-06-29 16:43:26.282463 | 5254009b-c4f4-9d47-3a71-000000001568 | CHANGED | Reboot after kernel args update | compute-0 2022-06-29 16:43:26.284191 | 5254009b-c4f4-9d47-3a71-000000001568 | TIMING | tripleo_kernel : Reboot after kernel args update | compute-0 | 0:02:08.911016 | 61.48 Jun 29 16:42:25 compute-0 sudo[8432]: heat-admin : TTY=pts/0 ; PWD=/home/heat-admin ; USER=root ; COMMAND=/bin/sh -c echo BECOME-SUCCESS-eyvpiolvjyamgfqelfehjvwywytvpere ; /sbin/shutdown -r 0 "Reboot initiated by Ansible" Jun 29 16:42:25 compute-0 systemd-logind[883]: System is rebooting (Reboot initiated by Ansible).
