    The proscribed driver update did not fix this issue.

    We are working with Nvidia to find a fix. As a stop-gap nodes which get stuck/flagged will be marked in Slurm for reboot and rebooted once empty of jobs.

    If a A100 GPU host your lab owns is stuck in a bad state, please let us know and we will mark and reboot it.
