Symptom & Impact

Host fails to boot fully and dumps a kernel oops with stack trace in dmesg.

Environment & Reproduction

Observed after a kernel upgrade on hardware with proprietary drivers.

Root Cause Analysis

Driver compiled against previous kernel ABI fails to load on the new kernel.

Quick Triage

Boot the previous kernel from GRUB and capture `journalctl -k -b -1`.

Step-by-Step Diagnosis

Identify the failing module from the oops trace.

Solution – Primary Fix

Reinstall the driver via `akmods` or DKMS against the new kernel and reboot.

Solution – Alternative Approaches

Boot a known-good kernel from GRUB while preparing the fix.

Verification & Acceptance Criteria

Host completes boot and no oops appears in `journalctl -k`.

Rollback Plan

Pin GRUB to the previous kernel as fallback until the driver is validated.

Prevention & Hardening

Test new kernel images in staging before broad rollout.
