Comment 5 for bug 1500925

Sorry
It was wrong that I wrote on 27th Oct.
On first reboot everything was seeming ok but next reboots I had same.
And I had been tried too many thing and I installed too many drives and program.
Actually my observation was wrong and the problem still goes on.

So
I installed the OS 15.10 from the beginning
(I remove old OS but home directory still same due to several reason)
But the problem still goes on
I dont know what should I do.
