I encounter an error like the one below, although AMD does it, I get an error in Arm.

Seems to be a QEMU issue. You can define ENV QEMU_STRACE=1 that will show you trace of syscalls proxied by the emulator so you can find out the potential issue. If you find something you can open an issue on qemu tracker.
