Symptom & Impact

Kernel upgrade completes, but external modules fail and drivers stop working.

Environment & Reproduction

Common with GPU, virtualization, and storage drivers managed by DKMS.

Root Cause Analysis

Missing headers or API mismatch causes module compile failures.

Quick Triage

Confirm active kernel and installed headers.

Step-by-Step Diagnosis

Inspect DKMS `make.log` for the first compile error.

Solution – Primary Fix

Install matching headers and rebuild DKMS modules.

Solution – Alternative Approaches

Boot a previous kernel until vendor-compatible module updates are available.

Verification & Acceptance Criteria

`dkms status` shows installed modules for the running kernel and functionality restored.

Rollback Plan

Reboot into prior kernel and remove failed module version if needed.

Prevention & Hardening

Validate DKMS compatibility in staging before production kernel rollout.
