I had a quick try to make it work, but no success thus far. Should it
be enough to apply the patch and then boot with "console=/dev/hvc0"?
Also, why do you comment out the EARLY_PRINTK stuff in Kconfig?

Works for me.> Also, why do you comment out the EARLY_PRINTK stuff in Kconfig?Doesn't compile due to setup_early_printk() being gone. I also think we don't need early_printk in xen any more. The hvc console supports a two-step setup. One can be done very early at boot (hvc_instantiate) and one later on, once everything (memory, irqs) is up and running, during normal device initialization (hvc_alloc). I'm still playing with it a bit and browse through the console code. Right now early hvc initialization happens in console_init, I'll try to do it earlier at boot. cheers, Gerd -- Gerd Hoffmann <kraxel@suse.de>
