I think we need these cherry picks to fix this for 3.18 and 4.4 v3.18 = https://chromium-review.googlesource.com/#/c/422413/ v4.4 = https://chromium-review.googlesource.com/#/c/422573/

I just built a kernel with this patch and the error seemed to go away. I'll try to merge these in asap

I just downloaded the newest official build and booted my Clapper on it. Everything appears to be working smoothly now. I believe this is fixed. (Should be fixed on any builds >=9149.0.0, I actually tested it on 9150.0.0 though)
