Symptom & Impact

Kernel upgrades can expose module incompatibilities on specific hardware.

Environment & Reproduction

System reboots into panic loop before reaching normal target.

Root Cause Analysis

Nodes with proprietary drivers, custom modules, or unusual storage controllers.

Quick Triage

New kernel cannot load required module or has incompatible boot parameters.

Step-by-Step Diagnosis

Capture panic trace and identify last loaded module.

Solution – Primary Fix

Boot known good kernel and blacklist problematic module if needed.

Solution – Alternative Approaches

Validate kernel and driver matrix in staging before broad rollout.

Verification & Acceptance Criteria

Host boots repeatedly without panic under normal workload.

Rollback Plan

Keep fallback kernel and staged canary update process.

Prevention & Hardening

Alert on failed boot checks and repeated crash signatures.

Related Errors & Cross-Refs

Pin previous stable kernel and postpone problematic package set.
