It would appear the linker has messed up the ALIGN(16), but it

expect zeros from 10100000 to 10100100, but maybe something
else is there.

I don't think this is directly related to the size of the kernel.


As usual, I'm wrong ;(

The problem is kernel size related.

Disassembly of section .text:

10100000 <stext-0x100>:
10100000:       20 2e b2 02     ldil L%1019d800,r1
10100004:       e0 20 2c 7a     be,n 63c(sr4,r1)
...

We have a bunch of long branch stubs at the beginning of the kernel.
