Mhm, your dmesg looks like you are still booting the standard Ubuntu kernel: [ 0.000000] Linux version 3.13.0-24-generic (buildd@batsu) (gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) ) #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 (Ubuntu 3.13.0-24.47-generic 3.13.9)
Grub usually selects the kernel with the highest version number for boot. Please double check that you selected the self compiled version in grub while booting.
Sorry, that wasn't the problem since I patched the ubuntu kernel itself, but I did forgot to update the initramfs, thus it was still loading the old module -_-.
Anyway, once I fixed it this works like a charm! Thanks a lot (and sorry again for the trouble)!
