If it is only happening when you start LiveTV, then I think I get that
too in 0.28-fixes.  It is quite reproducible for me - if I use LiveTV
to manually test all of my tuners (3 x DVB-T, 2 x DVB-S2), then it is
likely to lock up at some point.  Since I do not use LiveTV except for
testing tuners, I have not bothered to try to track down the problem
yet.
