My aim is not to revert a commit but to discover what the actual bug is and get it fixed in upstream stable 6.8 tree.
I've isolated it to kernel-only by eliminating both firmware (UEFI) and boot-loader (GRUB) from the equation with: qemu-system-aarch64 -machine virt,gic-version=3 -cpu max,pauth-impdef=on -smp 2 -m 4096 -nographic -kernel ./vmlinuz-6.8.12-arm64-debug -append "debug param146=ni4ohneo0oothieyeef9vo4ieth4yeiz6ohsiemae6aoy2asu9xei5eethoh0igaitha7laeghoothaeph9xai7kier3aib7aejaengahghan2zojeebai3kad9meesh6eichaey2" This will hang. Removing one character from param146= so it is actually 145 characters and the kernel will start. Now I have a minimal reproducer I can attach gdb and debug it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069534 Title: linux 6.8 fails to boot on arm64 if any param is more than 140 chars To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2069534/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
