Above address indicates that some loadable program segment is not
page size(4K) aligned hence kexec is cribbing.
A, "readelf -l /boot/bsd" should display the various program headers.
I think you shall have to modify linker script of OpenBSD kernel to
generate page size aligned loadable segments.
This does raise a question in my mind, why all the program headers
should be loaded at page size boundaries? Just because ease of handling
or there is some other reason too?
Eric, you want to shed some light on this requirement?
