--- Comment #52 from shui yangwei <yangweix.shui at intel.com> ---
By co-work with Terence and QNAP(one company of taiwan), we have been sure that
this issue already gone on latest -next-queued kernel. I reproduced this issue
by using QNAP's older kernel. Both loop running 100 times and only the kernel
is different, you can clearly see the results:

Physical environment:
------------------------
1. two of the same monitor
2. Both DP plugged
3. I haven't changed the X in the machine which Terence shipped to me. 

Test Results:
------------------------
1. older kernel: 
   One DP monitor will come up a warning message “DisplayPort no signal”, and
the other one always be OK. In my tests, the reproduce rate almost 10%(Totally
loop running 100 times X start and stop).

2. latest -next-queued kernel:
------------------------
Worked perfect. loop running 100 times X start and stop, all passed.But the
latest kernel has another issue(It's not related to this bug):
Bug #65287 - [IVB regression dp] *ERROR* mismatch in adjusted_mode.flags
(expected 1, found 0)

So we get a conclusion: this bug has been fixed on latest kernels. We can close
it now.
