Thanks for the fast reply!

I will do a run with the debug information as soon as I can and I'll post the
dmesg output.

About that error message, from what kernel version should it be fixed? I am
running the lastest RC I found prebuilt for ubuntu, unfortunately I don't have
too much time to build newer kernels.

Thanks -
