Re: Signal 8

I am not using floating point in the kernel. Only reference to floating 
point I founf was in rtai module rtai_sched, which provides floating 
point library.  I loaded this module with

insmod rtai_sched.o LinuxFpu=0

There is should be no floating point support (after LinuxFpu switch), 
but system still crashes with signal 8.

Other rtai modules are rtai_fifo and rt_mem_mgr
