I can reproduce the issue in a QEMU aarch64 virtual machine with both Ubuntu and Debian v6.8* kernels booting in EFI mode via GRUB, but here the length of the parameter that triggers it is 146 characters; eg:
linux /boot/vmlinuz-6.8.12-arm64 root=uuid=06bc9a44-31ef-41b1-bfe1-e6383822dccd ro console=earlycon efi=debug debug earlyprintk param146=ni4ohneo0oothieyeef9vo4ieth4yeiz6ohsiemae6aoy2asu9xei5eethoh0igaitha7laeghoothaeph9xai7kier3aib7aejaengahghan2zojeebai3kad9meesh6eichaey2 And the kernel hangs in the EFI libstub just after exiting boot services. I'm instrumenting the code to get to the root cause. -- 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
