bdw doesn't have rps support yet ... or the test makes some assumptions which are broken on bdw. Assigning to Ben.
Can you please run the pm_rps binary without and options (so that all subtests get run) and attach the entire output of the test? Please also set IGT_LOG_LEVEL=debug for added diagnostics. So # IGT_LOG_LEVEL=debug tests/pm_rps There will be lots of output so please attach as a file, not comment.

Looking at the log file, I think it's quite possible this is missed down interrupts which is meant to be implemented by Daisy Sun. We're expecting a patch for that shortly.
Please retest on latest drm-intel-nightly.
Works well on latest -nightly kernel.
Closing old verified.
