I happen to have tip installed on a dev box, so I thought I'd install a quad-hd and test for the issues you'd mentioned. I do not see any of the issues you are describing, regardless of whether I tested with w_scan, tzap, dvbtraffic. No unusual module options used, everything 'default'. Everything looks fine to me, no fault found, Ubuntu 16.04 Kernel 4.12-rc1, 64bit. -- Steven Toth - Kernel Labs http://www.kernellabs.com
