This means your inline assembly code is buggy.  Looking at it, my
first suspect is having %edx in the clobber list, but also "d" in the
inputs.  This can't work.  Same for "b" vs. %ebx, I guess.  Anyway, if
you're going to mark practically everything as clobbered anyway,
there's not much point using extended assembly syntax.  A simpler

	asm volatile ("movx %edi, _bank_number\n\
	     call *_pm_bank_switcher");

(syntax unchecked) would work just as well.
