> If I comment entire function setup_ring0_callgate content still same

Sorry, If I comment code of one function it reports error in another.
I traced some critical lines,
it happeded in inline AT&T assembly e.g.

"lcall *%5\n"                      // far call the CallGate to enter
ring 0, require code far return

or

asm __volatile__ ("sgdt %0" : "=m" (*gdtr)) // precte obsah GDTR
registru [mem48]

but other inline instructions like "cli" / "sti" passed.
