The SMP ones seem to fail with some regulator issues?


There is another problem, introduced with 6a0712f6f199e ("PM / OPP: Add
dev_pm_opp_set_rate()"). The kernelci boot log for next-20160212:omap3-overo-tobi
and others experience that problem.

Essentially, the code now assumes that a CPU clock always has a voltage
regulator attached to it, which is not correct. I sent out a patch to fix
that problem a minute ago.

Yes that fixed it thanks.


Confirmed. With this patch plus mine, all arm qemu tests are again passing for me.

Thanks,
Guenter
