The above suspend failure for nyan-big bisected to commit ce612879ddc7
("mm: move pcp and lru-pcp draining into single wq"). There have been
other reports of this breaking suspend [0] and has since been fixed [1]
for v4.11-rc7.

Interestingly this only was causing problems for tegra with XHCI enabled
(in tegra_defconfig). I am seeing some random usb resets during resume
with XHCI and so if anyone sees any such problems let me know.

Cheers
Jon
