Hi, [...] After a lot of bisecting, and comparing stable 8 branch (which works) with trunk, I've came to the conclusion that the commit 'Limit the size of the direct map with a 2MB granularity' [2] is actually causing the fault. I haven't been able to revert it on top of current trunk; however, I've been able to verify that with a later size fix included ([3]), the commit preceding it works and this one starts failing.
Please add some printfs like these right after 'va = efi_getva(pa)':
printf("pmap_direct_base = %p\n", (void *)pmap_direct_base);
printf("pmap_direct_end = %p\n", (void *)pmap_direct_end);
printf("va = %p\n", (void *)va);
printf("pa = %p\n", (void *)pa);
