Symptom & Impact

After reboot into new kernel, network or storage device is unavailable due to missing module.

Environment & Reproduction

Common with third-party DKMS drivers not rebuilt for latest kernel.

uname -r ; lsmod | head ; dmesg | grep -Ei 'module|firmware'

Root Cause Analysis

Kernel ABI change invalidates out-of-tree module binary and module autoload fails.

Quick Triage

Check module presence and recent kernel package transaction history.

modinfo  ; sudo dnf history info last ; sudo journalctl -k -n 120

Step-by-Step Diagnosis

Verify installed kernel headers and DKMS build status for active kernel.

rpm -q kernel-devel-$(uname -r) kernel-headers-$(uname -r) ; dkms status

Solution — Primary Fix

Install matching headers, rebuild driver module, and regenerate initramfs if required.

sudo dnf install -y kernel-devel-$(uname -r) kernel-headers-$(uname -r) ; sudo dkms autoinstall ; sudo dracut -f ; sudo modprobe 

Solution — Alternative Approaches

Boot previous kernel from GRUB while vendor-certified driver package is prepared.

Verification & Acceptance Criteria

Module loads cleanly and dependent device/service works after reboot.

lsmod | grep  ; systemctl status 

Rollback Plan

Select prior kernel via grubby if rebuilt module still fails stability checks.

sudo grubby --default-kernel ; sudo grubby --set-default /boot/vmlinuz-

Prevention & Hardening

Gate kernel patch rollout behind driver compatibility validation in staging.

Related Errors & Cross-Refs

Often linked to initramfs generation errors and secure boot signature rejection.
