Comment (by kgardas):

 Sebastian, thanks a lot for the information. Could you give me as much
 information as possible with regarding to the issue as there is a high
 chance I find some time to deal it again before your available timeframe.
 For example I'm curious is it related to FPU lazy stack saving which is
 used and enforced by the RTEMS code? Knowing all information about it from
 you, will certainly help with possible fixing of the issue on our side.
 Thanks a lot!
