That pretty much sums up what I was about to say ;-)

tp_printk is more of a hack and not to be used sparingly. With the right
trace events it can hang the machine.

So, you can use your internal patch locally, but I would recommend waiting
for the new printk changes to land. I'm really hoping that will be soon!
