I see. well, printk batching (buffered mode) is a bit tricky and we
don't have it, nor we recommend it. the main problem - you lose your
data on panic. it seems to me, that the only way to do it is to re-use
printk-safe buffer on that particular CPU. but it comes at a price and
in general is a bit ugly.
