The messages there suggest that your not allowed access the device. As Roy mentioned previously,
check /dev/fw0 and ensure your use has access:

try (as a normal user):
$ ls -l /dev/fw0

And check the permissions. Adding an "Audio" group is a good idea if you don't have one already.

Alsp check your memlock settings, as this line looks quite suspicous to me:
Cannot lock down memory area (Cannot allocate memory)

All the best, -Harry

PS: 1.9.x is known as JACK 2. Yup you've got JACK 2 :-D
