Apologies if this is the inappropriate method of contact. I was directed here from tvheadend's support forum. I have an Asrock Q2900-ITX with an RTL2838 USB DVB-T device (0bda:2838) that works out of the box on Kernels 3.19.0 (Ubuntu Vivid) and 4.0.5 (both distros). Unfortunately, while using the device, either system (my laptop or media center) will freeze. No response at all, power-cycle needed. I downgraded Arch to the 3.14.44 LTS kernel where everything seems stable. There's no log of kernel panicking. The only form of errors I could find at all are at the time of the freeze: kernel: [ 10.330935] show_signal_msg: 39 callbacks suppressed kernel: [ 10.330946] PVRManager[1212]: segfault at 18 ip 00007fecdf6fe929 sp 00007feca67fb430 error 4 in libc-2.21.so[7fecdf67d000+1c0000] Maybe this means something to you guys? I am willing to provide more information and stuff if you want. This is pretty alien to me. Thank you! Michael
