Hmm.
It turns out that commit c337104b1a16 ("ALSA: HD-Audio: SKL+: abort probe if DSP is present and Skylake driver selected") causes my laptop (XPS13 9350) to no longer suspend.
The screen goes dark, but the power light never turns off. There's nothing in the logs.

Sadly, that commit does not revert cleanly, since it's preparatory for a lot of other changes.
Here's the lspci output:
/sbin/lspci -s 0:1f.3 -vn 00:1f.3 0403: 8086:9d70 (rev 21) (prog-if 80) Subsystem: 1028:0704 Flags: bus master, fast devsel, latency 32, IRQ 16 Memory at dc328000 (64-bit, non-prefetchable) [size=16K] Memory at dc300000 (64-bit, non-prefetchable) [size=64K] Capabilities: <access denied> Kernel driver in use: snd_soc_skl Kernel modules: snd_hda_intel, snd_soc_skl
and it's a bog-standard Intel i7-6560U laptop.
I have no real information, except that I bisected the (reliable) behavior to this commit. Before that commit, suspend/resume works fine. After that commit, suspend just hangs and leaves a dead machine.
