Description

Prior to commit d59718e2, this is easily reproducible by adding . = . + 8192; into the kernel linker script, leaving enough space for kernel stack to be allocated in the created gap. Instead of booting properly and printing output, kernel will keep running but fills the screen with garbage.

If the stack is put after boot allocations, this does not occur, so that's what the workaround commit does.
However, the problem reoccurs if balloc is moved some distance (<600kB) from its usual position.
