FWIW, yesterday I checked my installations of RTAI (3.0r4 on 2.4.25 and
3.1 on for the cited problem.
The problem doesn't occur here, but when interrupting testsuite/user/preempt
with CTRL-C there was an error:
[translated message]
sleep: cannot read from realtime clock: unknown error 516

That error only occurs on 3.1/ when interrupting with CTRL-C.
If I just press ENTER it ends nominally. In any case, 'preempt' exits.

Best regards,
Hannes Mayer.
