Kdump-nfs test freezes on Arrow Lake systems with Intel I225/I226 NICs using igc driver

Solution In Progress - Updated -

Environment

  • Red Hat Enterprise Linux 9.6,9.3 and 9.2
  • Arrow Lake system with Intel I225/I226 NIC
  • Dell Pro Max Plus MB18250
  • Dell Pro Max Plus MB16250

Issue

The rhcert kdump test via NFS fails consistently on Arrow Lake - HX based platforms when using Intel I226 network interface cards. The system freezes when the kernel panic is triggered during the kdump test, preventing the device from rebooting and blocking the certification process.

Resolution

It will be resolved in upcoming kernel release.

Root Cause

The issue is caused by a bug in the RHEL 9.x kernel, specifically affecting Intel 2.5G network interface cards (I225/I226) that use the igc driver on Arrow Lake systems. The bug prevents proper kdump functionality during NFS operations, causing the system to freeze instead of successfully capturing and uploading the vmcore file.

Diagnostic Steps

  1. Check Hardware:

    # Verify network controller
lspci | grep -i ethernet

# Check for Intel I225/I226
lspci -v | grep -A 5 "I225\|I226"

  2. Verify Driver:

    # Check loaded network drivers
lsmod | grep igc

# Verify driver version
modinfo igc

  3. System Information:

    # Check RHEL version
cat /etc/redhat-release

# Verify kernel version
uname -r

# Check system architecture
lscpu | grep "Model name"

  4. Kdump Configuration:

    # Verify kdump service status
systemctl status kdump

# Check kdump configuration
cat /etc/kdump.conf
