@mikemckiernan could you please have a look at another addition to the precompiled drivers doc? |

The usual nits and suggestions. Thanks for updating the docs!
Add an important admonition to gpu-operator-with-precompiled-drivers.rst recommending manual upgrade approval, image tag validation, and pinning driver.version to a fixed tag to avoid GPU driver pods failing after an OpenShift cluster upgrade to an unsupported RHCOS kernel.

Adds an important admonition to
openshift/gpu-operator-with-precompiled-drivers.rstwarning about GPU driver pod failures caused by kernel/driver version mismatches during OpenShift cluster upgrades.OpenShift cluster upgrades automatically update node kernel versions. If a cluster upgrades to an RHCOS kernel for which Red Hat has not yet published a matching precompiled driver image in
registry.redhat.io/nvidia, GPU driver pods fail to initialize. Recovery is difficult, especially on Secure Boot-enabled nodes or in environments where local driver compilation is disabled. This note gives operators an actionable checklist to avoid the issue before upgrading.
