https://bugzilla.kernel.org/show_bug.cgi?id=20112 might be related, but at
least has additional data about my system (kernel config, lspci -vvv).

I can provide more information of course; please just ask.

I have just tried it again (I do not suspend to RAM normally), and it happened
again. This time I could get the output of the whole cycle from dmesg, which I
am attaching.
