Hi,With systems that have 8 GPUs nodes + an integrated BMC, the BMC can't work properly because of limits of DRM nodes in the kernel.
This is fixed in Linus tree with these commits: Can you please backport to 6.6.y and later? commit 5fbca8b48b30 ("drm: Use XArray instead of IDR for minors") commit 45c4d994b82b ("accel: Use XArray instead of IDR for minors") commit 071d583e01c8 ("drm: Expand max DRM device number to full MINORBITS") Thanks,
