Add my voice to those who don't think 4k stacks are a good idea as a
default, they break some things and seem to leave other paths (as others
have noted) on the edge. I'm not sure what you have in mind as a "better
kernel" but I'd rather have a worse kernel and not have to check 4k
stack as a possible problem before looking at other things if I get bad
behaviour.

Reliability first, performance later. We've lived with the config for a
while, pain there is better than pain at runtime.
