I've tried this patch on a box running 2.6.20 now for about a day and has not yet seen any i2c timeouts with it. I have tried to stress the i2c bus a bit by starting and stopping capture, retuning and browsing the MMI menus of the CAM quite a lot. I did however not see any pattern in when the i2c timeouts happened before applying the patch, so I can't possitivly confirm they are all gone. Thanks.
