Hello, I am looking for some advise on troubleshooting a issue I am seeing with mmap() (probably how I am using it). I have a issue where a driver returns a correct value, but it seem to get lost when that value is validated by mmap() and returns MAP_FAILED. Obviously gdb is not going to be able to set into the kernel and set through each call, so am I left with using ddb ? Any points/suggestions on dealing with this would be greatly appreicated.= =20 Thanks in advance.. Mike
