I am having similar problem with my BB 8520. Just that mine started recently and I have used the OS 5.0.0.1067 for about 7 months now. I could be in the middle of a call or running an application and it will just go off and show white screen. If I do a battery pool, I still get a white screen and unless I plug it to a charging system while it is restarting. Cant really understand what is wrong.
I have reloaded the OS 3 times already (the same OS) I use but I still get the same problem. Should I just downgrade or what? I cant fix a fix on what is causing the problem as I have removed all third parties applications in the BB just to see what happens. Still no success.
