Hi Mike, The attached patch should be queued for 2.6.29.X. It corresponds to changeset 11098 (v4l2-common: remove incorrect MODULE test) in our v4l-dvb tree and is part of the initial set of git patches going into 2.6.30. Without this patch loading ivtv as a module while v4l2-common is compiled into the kernel will cause a delayed load of the i2c modules that ivtv needs since request_module is never called directly. While it is nice to see the delayed load in action, it is not so nice in that ivtv fails to do a lot of necessary i2c initializations and will oops later on with a division-by-zero. Thanks to Mark Lord for reporting this and helping me figure out what was wrong. Regards, Hans -- Hans Verkuil - video4linux developer - sponsored by TANDBERG
