Apparently, it is a problem with tlb/command pipeline/hell-knows-more
This may be "illusion", I frequently find that adding arbitrary extra instruction or some random data can make bugs disappear. Usually it is moving symbols in the kernel image and either:
1) avoiding some linker bug 2) restoring some alignment constraint which is needed
Your change for example may have moved __init section into place which does not trip some bug in linker or something like this.
Experiment 8-)
