Created attachment 140634 [details] dmesg before and after S3 sleep with commit "updating plane ..." reverted
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.
