Description

The tests fix TC_rsl_ms_pwr_ctrl and TC_si_sched_13_2bis_2ter_2quater fail since a delay after RSL initalization was introduced. Since the failure also appears with with latest, the problem must have been triggered by the change in the testsuite.

I have analyzed the problem. For fix TC_rsl_ms_pwr_ctrl I can definitely say that the delay triggered the problem. However, I can see no direct connection between the delay and the testcase. The delay just causes to start the test later, but inside the test everything remained constant. Probably the delay before the test changed the conditions so that a race condition takes effect. I tried various things to relax the timing. I found out that it started working again when I wait for a short amount of time between the test loops.

A quick solution would be to remove the delay again. Its a module parameter anyway and the tests on real hardware can configure that accordingly.

The default settings remove the delay now:
