Bug description:
  Hi,

  During some autopkgtest debugging, we found that we were unable to
  boot an armhf virtual machine with more than 3GB of RAM.

  Here is the working command line:
  ```
  qemu-system-arm \
  -machine virt -m 3G -smp 2 -nographic \
  -object rng-random,filename=/dev/urandom,id=rng0 \
  -device virtio-rng-pci,rng=rng0,id=rng-device0 \
  -drive if=pflash,format=raw,unit=0,read-only=on,file=/usr/share/AAVMF/AAVMF32_CODE.fd \
  -device virtio-net-pci,netdev=eth0 \
  -netdev user,id=eth0,hostfwd=tcp::8022-:22 \
  -drive file=autopkgtest-noble-armhf.img,if=virtio,format=qcow2
  ```
  And here is the broken one, that ends up in a loop of `watchdog: BUG: soft lockup - CPU#1 stuck for 26s!`:
  ```
  qemu-system-arm \
  -machine virt -m 4G -smp 2 -nographic \
  -object rng-random,filename=/dev/urandom,id=rng0 \
  -device virtio-rng-pci,rng=rng0,id=rng-device0 \
  -drive if=pflash,format=raw,unit=0,read-only=on,file=/usr/share/AAVMF/AAVMF32_CODE.fd \
  -device virtio-net-pci,netdev=eth0 \
  -netdev user,id=eth0,hostfwd=tcp::8022-:22 \
  -drive file=autopkgtest-noble-armhf.img,if=virtio,format=qcow2
  ```
