Hi, I got a similar crash now with USB-2.0. Took longer to happen, but did, see attached log. This makes it more likely the problem is located in DVB code not USB. Will try it on my PC now. At least I already get messages like kernel: [680947.641704] technisat-usb2: i2c-error: 60 = 7 If it crashes again, I can complain at Ubuntu ;) > Do you see the same issues with a 3.19 rc kernel? Will try. Currently cloning git repo, so I can better track my builds. thanks for your help, Jan
