Hello Kohei This is a known limitation,
Using cpu=max might expose new features that EDK2 support is missing or incomplete, thus, causing boot instability. The good practice is to use a well defined CPU model, like you mentioned in the bug report: neoverse-v1 Is there any reason you have to use cpu=max instead of a defined CPU model ? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2167864 Title: EDK2 hangs when launched with qemu-system-aarch64 -cpu max To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/edk2/+bug/2167864/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
