That's not really informative. It just tells some parms exist.

Nothing in the logs, the laptop just freezes for a short while then
continues. And resume from suspend is quite painful, with sometimes
some long wait before having GDM usable.
But I've found a (heavyhanded) workaround: I installed Ubuntu 16.10
instead of Debian strech and everything is working flawlessly now.
There are probably some kernel patches which have not yet been
upstreamed in there.
