Just to confirm: this was measured on eDP, right?

What about the other outputs?

On my BDW machine, with eDP, it takes 8m50s, so I guess it makes sense to reduce the number of iterations a little bit...

Yes attached eDP.

Test with HDMI, it takes about 8m35s.

I just pushed "tests/pm_rpm: reduce the number of rounds on the stress tests" to the IGT repository. This should put us way below the 10m mark. If the problem still happens, please reopen the bug.

Test on latest igt(commit 5c7d54eae5cbf9fd), it takes 4m10s. Close it.
