So no reservation left.  Whatever blocked the pci bar resource (efifb
probably) is gone now.

So the interesting question is why that reservation sticked long enough
to prevent bochs-drm from initializing.  In theory efifb de-init should
be completed when drm_fb_helper_remove_conflicting_pci_framebuffers()
returns.

Bisecting could help, or springkling printk's into efifb ...

I think that is just some eye candy which delays fbcon init until
something is actually printed.

Try "echo hello world > /dev/tty0".
Maybe tapping enter (to make getty re-print the login prompt) works too.

cheers,
