The call tree which we could (and actually always should) get into that state is xenfb_probe() -> register_framebuffer() -> fbcon_event_notify() -> fbcon_fb_registered() -> fbcon_takeover() -> take_over_console() -> bind_con_driver() -> visual_init() -> fbcon_init() -> xenfb_set_par(). Since xenfb_probe() calls register_framebuffer() before kthread_run() and xenfb_connect_backend(), xenfb_thread() should find info->resize_dpy always set to 1, and hence always go into xenfb_do_resize() right away (which, depending on the timing, would...

Hi Andi, This patch series implements the Linux Xen guest in terms of the paravirt-ops interface. The features in implemented this patch series are: * domU only * UP only (most code is SMP-safe, but there's no way to create a new vcpu) * writable pagetables, with late pinning/early unpinning (no shadow pagetable support) * supports both PAE and non-PAE modes * xen console * virtual
