Description
Description of problem:
Hi team, The initramfs image in [1] doesn't allow a correct boot, the process ends in a second or 2 with a generic kernel panic while using PXE setup.I attach a video of the boot process.I already checked the PXE configuration and it has no issues [2], I am able to boot from 4.12 without any issues by just replacing the highlighted files from 4.13 with 4.12 in the PXE folder. [1]https://mirror.openshift.com/pub/openshift-v4/x86_64/dependencies/rhcos/4.13/latest/ [2] DEFAULT bootstrap SAY Now booting the kernel from SYSLINUX... LABEL bootstrap KERNEL rhcos/rhcos-live-kernel-x86_64 APPEND initrd=rhcos/rhcos-live-initramfs.x86_64.img coreos.live.rootfs_url=http://192.168.101.4/metal/rhcos-live-rootfs. x86_64.img coreos.inst.install_dev=/dev/vda coreos.inst.ignition_url=http://192.168.101.4/metal/bootstrap.ign
Version-Release number of selected component (if applicable):
4.13.0
How reproducible:
Steps to Reproduce:
Follow OCP 4.13 any platform setup. Download initramfs, kernel and rootfs from https://mirror.openshift.com/pub/openshift-v4/x86_64/dependencies/rhcos/4.13/latest/ or any other folder 4.13 related. Configure PXE following the docs. Kernel panic on bootstrap node boot.
Actual results:
Kernel Panic after 1.3s in the boot chain
Expected results:
Successful PXE boot.
Additional info:
Just replacing the initramfs with a 4.12 image make the boot proceed, and it breaks on kernel load due to mismatching versions. Correct initramfs + kernel + rootf from 4.12 latest work like a charm.
