    iso: pin NVIDIA driver/DCGM to DGX OS 7.5.0-validated combo

    mchus released this 2026-07-06 13:33:52 +03:00 | 97 commits to main since this release

    590.48.01/DCGM 4.6.0-1 was never a deliberate compatibility choice — the
    driver version traces back to a CDN 404 on the originally pinned
    550.54.15 (commit 559fc29), and DCGM was bumped twice since purely
    because NVIDIA pulled the previously-pinned core package from the repo
    (6dee8f3, b2e177a). The 590 branch only has two point releases so far,
    and its nvvs plugin fails dcgmi diag with "Detected driver major
    version 0 is not between the required versions 346 and 2000" on H100 —
    confirmed via a staging support bundle.

    Switch to 580.126.20 / DCGM 4.5.2-1, the combo NVIDIA's own DGX OS 7.5.0
    release notes validate for H100. Both packages confirmed present in the
    NVIDIA CUDA debian12/x86_64 apt repo.
