I don't do suspend on this laptop, I poweroff and reboot when I get

ALSA: hda - Fix possible runtime PM refcount unbalance
That landed in next-20150324 - which is broken for me.
Looks worth trying a revert before I bisect, thanks for the hint, will
report back (probably tomorrow) on what happens...
