Comment 162 for bug 1518457

same problem here, c720p chromebook , happens on several different distros like arch, ubuntu, xubuntu. I downgraded to the 4.1.x kernel and the issue is less frequent (needs much more memory pressure to trigger). then I downgraded to the 3.17 kernel and the issue is gone completely. all the previous suggestions and workarrounds didn't work for me. only downgrading the kernel did.
