Philby, I tried running this patch against 2.6.31.rc2 (davinci kernel tree). But I got a crash as I run the application which is given below.... In my case, time out happens when I kill the capture application using Cntrl-C. After Cnrtl-C, the mt9t031 i2c device couldn't be contacted by the host (during cleanup, i2c commands fails). When the application is run again, I get following outputs.. i2c_davinci i2c_davinci.1: timeout waiting for bus ready i2c_davinci i2c_davinci.1: timeout waiting for bus ready Here are the complete log.... application running and pressed Cntrl-C ====> time:105 frame:33 time:105 frame:34vpfe-capture vpfe-capture: stream off failed in subdev Running it again ..... root@xxxxxxxxxxxxxxx:/opt/git#
