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