All the more reason to continue then, even if only for nostalgia ;)

Jokes aside, I do run -next kernels regularly for my daily drivers 
(which are x86_64), but it's honestly not very often I notice bugs there 
that affect me. They have all been pretty minor or very obvious and 
would probably have been caught regardless, but I'll of course still 
report them.
