When trying to run sysutils/vbetools (installed via pkg) with any arguments I see "mmap /dev/mem: Invalid argument" and then "Failed to initialize LRMI (Linux Real-Mode Interface)". Output of truss: mmap(0x0,1282,PROT_READ|PROT_WRITE|PROT_EXEC,MAP_SHARED|MAP_FIXED,3,0x0) So my guess is that the combination of hint address 0 and MAP_FIXED does not work. Tested FreeBSD versions are 9.1, 10.2 and 10.3.
Same with Freebsd 11.2/amd64
Maintainer feedback, please!
