https://bugzilla.suse.com/show_bug.cgi?id=1226497 Bug ID: 1226497 Summary: No boot from software RAID after upgrade to 15.6 on Supermicro H12DSi-NT6 Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: x86-64 OS: Other Status: NEW Severity: Major Priority: P5 - None Component: Bootloader Assignee: screening-team-bugs@suse.de Reporter: georg.pfuetzenreuter@suse.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- Hi, this follows https://progress.opensuse.org/issues/162401. Background: We have several hypervisors with a software RAID (MDADM) setup, which also houses /boot and /boot/efi. This always worked very well on Supermicro platforms and avoided the need for additional tricks to keep the EFI partition redundant and in sync. Situation: The upgrade to 15.6 on one such machine (with a Supermicro H12SSL-NT board) worked fine. A second machine (with a Supermicro H12DSi-NT6 board) however freezes at POST during the reboot while printing "Ready to boot" (after which it would usually execute to the OS bootloader) after the 15.6 upgrade. Entering a chroot from a live environment, downgrading the GRUB packages to the ones used on 15.5 grub2-2.06-150500.29.25.12.x86_64.rpm grub2-i386-pc-2.06-150500.29.25.12.noarch.rpm grub2-x86_64-efi-2.06-150500.29.25.12.noarch.rpm and `bash -x /usr/lib/bootloader/grub2-efi/install` makes the machine boot again. Advice would be appreciated - we have several more of the H12DSi-NT6 machines which we cannot upgrade to 15.6 because of this. -- You are receiving this mail because: You are on the CC list for the bug.
