My system boots into the 4k page-size kernel despite selecting the 64k kernel package during installation of Red Hat Enterprise Linux 10.2 for ARM64

Solution In Progress - Updated -

Environment

  • An aarch64-based system capable of supporting a 64k page size kernel
  • Red Hat Enterprise Linux 10.2 for ARM64

Issue

My system boots into the 4k page-size kernel despite selecting the 64k kernel package during installation of Red Hat Enterprise Linux 10.2 for ARM64

Resolution

A dependency issue in the iptables family of packages included with the GA release of Red Hat Enterprise Linux 10.2 for ARM64 is causing the installation of the 4k page-size kernel even when the 64k page-size kernel is selected at install time. A fix for this issue is being tested and is expected to be available in a future update release of RHEL 10 for ARM64. Note that this problem first appeared in RHEL for ARM64 10.2. Versions 10.0 and 10.1 of RHEL for ARM64 are unaffected.

Until the fix is available you may use the following command post-install to set the 64k kernel to be the default, then reboot to begin using the 64k kernel.

$ sudo grubby --set-default=`echo /boot/vmlinuz*64k`
