Description nkoch 2018-08-06 08:27:29 UTC 
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.
