I think I was able to find a temporary solution..
I too had this issue in my iPad air after the iOS 8 update.
I dropped my iPad in an apple service centre, for 1-2 days. Even though they tried to replicate the bluescreen through many tests, it didn't happen at least once, so they gave it back to me saying, it's good. So I thought of trying to find the cause.
It's mosly happening when I use apps made by apple, like pages, numbers,Safari etc. So I thought I should test these apps. Finally, I was able to find a temporary solution.
Just turn off the iCloud sync for all the apps..
I had bluescreen restarts once in every 10-20 minutes in my iPad air when browsing in Safari. But after turning off the safari iCloud sync from,
settings->iCloud, my iPad is working fine..
It's been some hours since I'm browsing.
So I guess, this will work with other apps, like pages:
settings->pages->use iCloud (turn off)
Hope this works for some of you..
It's not a cool thing to turn off iCloud sync, but for the time being, until apple release an update to fix this, it's a way to save ourself from losing data and frustration.
Have a wonderful time..
