This is my dmesg:

This is what slots look like:
ubuntu@ubuntu-armhf:~$ cat $SLOTS
0: 54:PF---
1: 55:PF---
2: 56:PF---
3: 57:PF---
Where did 4 and 5 go???
Why do I get a failure to resolve device tree if I attempt to load an
overlay?

This is using a boot off sd card. When using the shipped eprom debian
system(3.8.13 bone48, the slots file looks correct and I can load overlays.
So I am guessing it is something in the 3.8.13-bone20 image. Is there a
stable Ubuntu using a kernel that supports cape manager? I'd really like
to do PWM off the GPIO pins.
