None of the driver changes are relevant to this system.  You are not
using Hyper-V and Linux 6.1 does not include the USB drivers that
initramfs-tools tries to add.

I can't reproduce this.

I suspect that probing of your USB keyboard is slightly unreliable and
that it just happened to fail on the first boot after you upgraded. 
Please try again with the new initramfs-tools packages.  Also, if the
keyboard is not detected at first, try unplugging and re-plugging it.

If this problem persists, please send:

- The /etc/initramfs-tools/initramfs.conf file
- The output of "lsinitramfs /boot/initrd.img-6.1.0-25-amd64" when
  the old version of initramfs-tools is installed
- The output of "lsinitramfs /boot/initrd.img-6.1.0-25-amd64" when
  the new version of initramfs-tools is installed

Ben.
