The thread you are referring to describes the issue as happening inside
some emulator (virtualbox), and clearly shows that the a solution was
implemented (Xenomai refuses to start if the reported frequency is 0,
instead of crashing with a division by 0).
If you have this issue when running inside an emulator, then the
emulator needs fixing, if you do not run inside an emulator, then the
issue is a different one, and the thread you refer to is irrelevant.
