I've been digging some more through the memory and determined the following:
- bzImage loaded at 0x1a32200 though first 0x3e00 are zeroed
Dumping sizeof(bzImage) bytes starting at 0x1a32200 and comparing it
with original bzImage I get (offset relative to bzImage start):
0x00003e00 .. 0x0016cfff matches
0x0016d000 .. 0x009bcfff mis-match
0x009bd000 .. 0x009c687f matches
.. 0x009c69af partial mis-match
memory mis-match (bzImage has data in there):

Now my question is, what does the zeroed area correspond to?
The start of zeroed area in memory would be:
0x1b9f200 .. 0x23ef1ff
For both starting kernels this fully fits into mem04.
So I'm wondering why the data does not match!
Just to get this kind of issues detected at a time it's possible to render some error
message, could the stub check its payload (CRC or better hash) before calling exit_boot
so a efi_printk() would still be possible?
