The media-build HEAD revision was commit e4a8d40f63afa8b0276ea7758d9b4d32e64a964d Author: Hans Verkuil <hans.verkuil@xxxxxxxxx> Date: Wed Jun 18 10:27:51 2014 +0200 dmesg.2 is from 3.8.0-42 with the ubuntu-provided modules and does not show the issue. The issue occurs in later ubuntu kernels, 3.11 as noted previously and 3.13.0-30. The OS is ubuntu 12.04 LTS, amd64. I looked into bisecting this but could not figure out a procedure since the 'build' script tries really hard to use the latest media-build and kernel sources. It looks like one has to run the media-build 'make' against a checkout of the vanilla kernel that roughly corresponds in time (or at least is not from a time later than the current media-build revision that is checked out). Please respond this time Vince
