Abstract

Based on a recent Red Hat Security Advisory (https://access.redhat.com/errata/RHSA-2025:15668) that was released on September/11/25 for RHEL9.4, kernel 5.14.0-427.87.1.el9_4 (and higher el9_4 kernels) may cause an IBM Fusion deployments running Global Data Platform/Global Data Platform remote mount service pods to crash and prevent it from coming online after a reboot.

Content

According to information from Red Hat Security Advisory 2025:15668 (https://access.redhat.com/errata/RHSA-2025:15668) for RHEL 9.4, the EUS kernel 5.14.0-427.87.1.el9_4 (and higher el9_4 kernels) may cause Global Data Platform/Global Data Platform remote mount pods to experience a kernel crash and prevent the node that applied the patch from coming online after a reboot. Based on this advisory, the kernel 5.14.0-427.87.1.el9_4 and higher el9_4 kernels should be avoided and not patched on IBM Fusion systems until a fix is available with the resolution. 

Users Affected:

  • All IBM Fusion HCI or IBM Fusion users who upgrade to Red Hat OpenShift z-stream across OpenShift 4.16 (4.16.48+), 4.17 (4.17.40+), and 4.18 (4.18.24+). 

Problem Determination:

The problem symptom is a kernel crash when you start Global Data Platform/Global Data Platform remote mount with RHEL 9.4 EUS kernel 5.14.0-427.87.1.el9_4 and higher el9_4 kernels.  

Recommendations:

All IBM Fusion HCI or IBM Fusion users running upon OpenShift 4.16, 4.17, 4.18 should wait until the fix is available before updating any OpenShift z-stream levels that install 5.14.0-427.87.1.el9_4 or later.  

Note: This equates to OpenShift versions 4.16.48+, 4.17.40+, and 4.18.24+.  

Resolution:

For IBM Fusion 2.11 version, apply the resolution steps mentioned in the hotfix.
