https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214718 --- Comment #2 from commit-hook@freebsd.org --- A commit references this bug: Author: emaste Date: Fri Nov 25 18:57:14 UTC 2016 New revision: 309151 URL: https://svnweb.freebsd.org/changeset/base/309151 Log: Use explicit 0x200000 instead of MAXPAGESIZE for the amd64 kernel physaddr MAXPAGESIZE is not well defined by the GNU ld documentation. Different linkers, and different versions of the same linker, use different MAXPAGESIZE values. Current versions of GNU gold and LLVM's lld use 4K. When set to 4K the kernel panics at boot due to an issue with x86bios. Here we want the kernel physaddr to be the amd64 superpage size, so use that value (2MB) explicitly. With this change GNU gold and LLVM lld can link a working amd64 kernel.
