@WayneWWW Thanks for the fix instructions, solving my mystery of why my AGX suddenly _started_ working after multiple reboots, and the bootloader details. I didn’t even get a chance to apply the manual fix since it appears a new package does fix the boot command line arguments. ```nohighlight $ sudo apt update && sudo apt dist-upgrade Get:1 file:/var/cuda-repo-10-2-local-10.2.89 InRelease Ign:1 file:/var/cuda-repo-10-2-local-10.2.89 InRelease Get:2 file:/var/visionworks-repo InRelease Ign:2 file:/var/visionworks-repo InRelease Get:3 file:/var/visionworks-sfm-repo InRelease Ign:3 file:/var/visionworks-sfm-repo InRelease Get:4 file:/var/visionworks-tracking-repo InRelease Ign:4 file:/var/visionworks-tracking-repo InRelease Get:5 file:/var/cuda-repo-10-2-local-10.2.89 Release [574 B] Get:6 file:/var/visionworks-repo Release [2,001 B] Get:7 file:/var/visionworks-sfm-repo Release [2,005 B] Get:5 file:/var/cuda-repo-10-2-local-10.2.89 Release [574 B] Get:8 file:/var/visionworks-tracking-repo Release [2,010 B] Get:6 file:/var/visionworks-repo Release [2,001 B] Get:7 file:/var/visionworks-sfm-repo Release [2,005 B] Get:8 file:/var/visionworks-tracking-repo Release [2,010 B] Hit:9 https://repo.download.nvidia.com/jetson/common r32.4 InRelease Hit:10 https://repo.download.nvidia.com/jetson/t194 r32.4 InRelease Hit:11 http://ports.ubuntu.com/ubuntu-ports bionic InRelease Hit:13 http://ports.ubuntu.com/ubuntu-ports bionic-updates InRelease Hit:14 http://ports.ubuntu.com/ubuntu-ports bionic-backports InRelease Hit:16 http://ports.ubuntu.com/ubuntu-ports bionic-security InRelease Reading package lists...
