Reverting the patch makes the TTM eviction failure + following driver resume
failure go away. So that one issue. Another issue Is that you still experience
page table updates realated fault during S3. I can't reproduce that issue. 

I am currently looking into how this patch broke S3, this is more burning issue
as other people experience it to. Later i will try to give you some debug
printk patch to sort out your page fault issue.
