Description of problem: After install rt kernel, configure hugepage and reboot server, kernel got panic status Version-Release number of selected component (if applicable): rt kernel version: kernel-rt-4.18.0-241.rt14.6.el8.dt1 kernel-rt-4.18.0-240.10.rt14.5.el8 How reproducible: Always Steps to Reproduce: 1.install target rt kernel. 2.configure hugepage as below: #echo "vm.nr_hugepages = 20" >> /etc/sysctl.conf #/usr/sbin/grubby --args="default_hugepagesz=1G" --update-kernel=`/usr/sbin/grubby --default-kernel` 3.#systemctl stop irqbalance.service 4.#/usr/sbin/chkconfig irqbalance off 5.#/usr/sbin/swapoff -a 6.reboot server Actual results: Expected results: system can reboot smoothly and the configuration of hugepage can be effected in system. Additional info: for kernel-rt-4.18.0-240.10.rt14.5.el8 the grub info as below: index=0 kernel="/boot/vmlinuz-4.18.0-240.10.rt14.5.el8.x86_64" args="ro intel_iommu=on ksdevice=bootif crashkernel=auto resume=/dev/mapper/rhell _dell--per740--05-swap rd.lvm.lv=rhel_dell-per740-05/root rd.lvm.lv=rhel_dell-pee r740-05/swap selinux=0 console=ttyS0,115200n81 $tuned_params default_hugepagesz== 1G" panic info as below: Welcome to Red Hat Enterprise Linux 8.4 Beta (Ootpa) dracut-049-95.git20200804.el8 (Initramfs)!
