I agree that printk is fragile and your patches are likely fine for machine where you do kernel development. However for production servers with hundreds of SCSI LUNs assigned I don't think it is a viable solution - I'm pretty sure those machines would take ages to boot (if they ever boot) with early_printk implementation. So do you intend this as "the ultimate printk solution" or just a "kernel developers debugging aid"? :)
