I got call issue whenever Titan Kernel is installed, either the old power 40, 42 in extras or 46 in extras devel. Sometimes my N900 sounded like twisted cassette tape, sometimes the other end said my voice was too chokky choppy they could not understand what I was saying. That happened even when I did nothing else except making or receiving calls. A recall usually resulted good quality.

Without the kernel power, much less call issue occurs. I decide to stay away from the tempted Titan Kernel Power untill the call issue is fixed. Maybe this is just my device's issue (on 3G network) because I have not found any other with similar problems.

I checked by reflashing the device with both fiasco and eMMC images, making a call (good quality), installing the Titan Kernel without anything else, rebooting, making a call (call issue occurs); reverting back to original Nokia kernel, rebooting, making a call (good quality again.)
