[mythtv-users] Mythbuntu 14.04: Problem after kernel upgrade

[Grzegorz Sikorski]

Thanks Mike, that helped. I did similar things before, but it did not work.
The only thing I have changed in the procedure in compare to my own is
building as a root (previously I only installed with sudo). This is
something I cannot really explain, but does not matter now.
