+Mac M1 Max / Debian guest / Luks password / Switching to graphical login manager (lightdm/Gdm) hangs in 75%
+Description of problem:
+In approximately 70% of cases I start QEMU with a Debian guest where the Debian guest was installed with full disk encryption, QEMU 'hangs' (does not respond') after I unlock the encrypted guest and the guest tries to start the graphical login manager (gdm or lightdm).
+
+I need to force quit QEMU, restart it multiple times until the start of the graphical login manager works.
+Steps to reproduce:
+1. Install Debian with (guided) full disk encryption and either the Gnome or the XFCE desktop environment
+2. To be able to unlock the hard disk after the installation finished, the Linux boot parameter 'console=tty1' needs to be added within grub to the Linux command line
+3. Try to restart/reboot QEMU  several times and QEMU will become unresponsive multiple times in this process.
+Additional information:
+I encounter this problem for several months now, with different versions of QEMU, macOS and Debian.
+
+There is one observation, which might help: I installed [DropBear](https://packages.debian.org/buster/dropbear-initramfs) to experiment with remote unlocking of Luks encrypted Linux boxes. It seems, that QEMU does not go into the unresponsive state, when I unlock the hard disk via SSH and not focus the QEMU window until after the graphical login manager started. (Only tried remote unlocking a few times so it is too early to confirm if this works 100% of the time.
