I was on the right track with the thinking that drivers are loaded at first, but then xhci can't unload when the resume happens. The solution was to blacklist xhci. Edit /etc/modprobe.d/xhci.conf: blacklist xhci Then update initrd.img: # update-initramfs -u That's it, now suspend to ram and suspend to disk work!
