This error is defined in src/sys/amd64/amd64/machdep.c Changing the following define: #define PHYSMAP_SIZE (2 * 8) to #define PHYSMAP_SIZE (2 * 16) has solved the problem, the machine boots and works without any noticeable side effect. Are there any reasons to keep this and not to increase PHYSMAP_SIZE?
