Subject: Qemu v9.0.2: Boot failed qemu-arm64 with Linux next-20241017 tag

The QEMU-arm64 boot has failed with the Linux next-20241017 tag.
The boot log is incomplete, and no kernel crash was detected.
However, the system did not proceed far enough to reach the login prompt.

Please find the incomplete boot log links below for your reference.
The Qemu version is 9.0.2.
The arm64 devices boot pass.

This is always reproducible.
First seen on Linux next-20241017 tag.
  Good: next-20241016
  Bad: next-20241017

qemu-arm64-protected:
  boot:
    * clang-19-lkftconfig
    * gcc-13-lkftconfig
    * clang-nightly-lkftconfig
