Author: dim Date: Sun Mar 6 15:57:43 2016 New Revision: 296428 URL: https://svnweb.freebsd.org/changeset/base/296428 Log: Since kernel modules can now contain sections of type SHT_AMD64_UNWIND, the boot loader should not skip over these anymore while loading images. Otherwise the kernel can still panic when it doesn't find the .eh_frame section belonging to the .rela.eh_frame section. Unfortunately this will require installing boot loaders from sys/boot before attempting to boot with a new kernel.
