An updated version of the tar file is attached.

dmesg.1 is from 3.8.0-38 plus media-build modules and shows the
firmware loading issue.
The media-build HEAD revision was
  commit e4a8d40f63afa8b0276ea7758d9b4d32e64a964d
  Author: Hans Verkuil <hans.verkuil@cisco.com>

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
