I already sent this question to the hardware list, but I think it's not really a hardware problem so I post this here again.
Hi, In the new Kernel of the latest FSO I noticed some changes. The config files for parameters like threshold, sample rate etc. are now in the following folders: Acc1: /sys/class/i2c-adapter/i2c-0/0-0073/lis302dl.1 Acc2: /sys/class/i2c-adapter/i2c-0/0-0073/lis302dl.2 When I read out the Acc values I get strange values. I set the device to 100 Hz that means I should get one (3D) value every 10 ms but I get two even with a different time stamp whitch differs round about 0.4 ms. Because of the axis orientation it cannot be from the second Accelerometer. So where does this additional (3D)value come from? This log I recorded from the first accelerometer with 100 Hz. (If set to 400 Hz I get two values every 2.5 milliseconds, the same problem) What's going wrong?

If I should open a ticket please tell me where to do that.
