I'm running Ubuntu12.04 with Groovy. Because of real-time, I installed a 3.10 kernel which runs ok, but when i start roscore it doesn't give the full expect output. The info is:

... logging to /home/huub/.ros/log/72c3c554-a90d-11e3-bd62-9ad1b1f98c51/roslaunch-BBxM-2548.log Checking log directory for disk usage. This may take awhile. Press Ctrl-C to interrupt Done checking log file disk usage. Usage is <1GB.

After this, nothing happens. Thanks for suggestions.

On the ROS website, I notice that ROS Hydro is supported for Ubuntu Raring which has kernel 3.8. Since I (try to) run Groovy on kernel 3.10, will that indeed give the problems I'm experiencing ?

Could you elaborate on "because of real-time"? Generally speaking the kernel version rarely affects high level things which are not interacting with hardware, such as roscore. However, if you are installing a real-time kernel, then all bets are off. Is that what you are doing?

Yes, because of the target-device I have to use real-time, and thus a real-time kernel. From your response I sense that roscore will very likely not run properly on a real-time kernel? I thought the incorrect functioning of roscore (Groovy) was possibly due to the 3.10 kernel since Ubuntu Quantal (kernel 3.5) is the last version supporting Groovy. So I was trying to get a 3.5 kernel running (experiencing some problems with that though).

Checking the logfile it ends with: xmlrpc][INFO] 2014-04-01 13:17:37,651: XML-RPC server binding to [xmlrpc][INFO] 2014-04-01 13:17:37,654: Started XML-RPC server [http://BBxM:35499/] [xmlrpc][INFO] 2014-04-01 13:17:37,656: xml rpc node: starting XML-RPC server So roslaunch server fails.
