 Even when I am not using the phone at all my logs get filled with kernel
 messages like

 this wastes disk space and makes finding the important stuff from logs
 more difficult. Please consider making these debug prints something that
 can be configured at runtime if they are really needed.

 (Ignore the ogsmd DEBUG messages, they are caused by my periodic watchdog
 that checks that the phone is connected to GSM network every 50 seconds.)

 I am reporting this bug against andy-tracking b8b36e5ec3db71d5 which is
 quite old. Please close this if the bug has already been fixed in newer
 kernels. I'll try to move to newer kernels when bugs #2255 and  #2257 have
 been resolved.
