[Vladimir Kuklin (vkuklin)]

Sergey, please, be more descriptive. Which node fails to boot? Master node or slave node?

[Sergey Skripnick (eyerediskin)]

Vladimir, new node when trying to boot into "bootstrap"

[Miroslav Anashkin (manashkin)]

Please check if kernel parameter "intel_iommu=off" solves the issue.
Add it with the following console command on master node:
`dockerctl shell cobbler cobbler profile edit --name bootstrap --kopts="intel_iommu=off" --in-place`

[Sergey Skripnick (eyerediskin)]

Miroslav, it works.

[Bogdan Dobrelya (bogdando)]

Setting to invalid then, please update if the issue still exists

[Dmitry Borodaenko (angdraug)]

Please document the workaround in the Ops Guide (how to pass kernel parameters to nodes, and about intel_iommu specifically).

[Vasilios Tzanoudakis (vtzanoudakis)]

The problem exists also on a Brand new Dell R620.
The command that Miroslav proposed above solved the issue.
