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
