With I-Pipe v2.4-03, Xenomai v2.5-devel (SVN revision 4519) and Linux
2.6.26 on my TQM85200 I get:

  -bash-3.2# ./fpu-exception-test
  Floating point exception

  -bash-3.2# dmesg|tail
  ...
  Xenomai: Switching trivial to secondary mode after
  exception #1792 from user-space at 0x10001840 (pid 1127)

Is that the expected behavior?

Wolfgang.
