Are we sure that the pipeline error is a separate cause of a freeze up? I've had a lot of freezes in Ubuntu 17.04 and the freeze has only once been accompanied by the pipeline update.
In my kernel logs, the pipeline appears once, but all seem to have the kernel BUG swapops.h, ( after --[cut here]--).
