Interestingly, this only seems to happen after the first s2ram.
https://bugzilla.kernel.org/attachment.cgi?id=72904 contains the dmesg from
three s2ram's, and after the second and third one write seems to be enough.
Even the failing firewire/card reader (another bug) is more quiet.
... (after the second s2ram, touchpad works after this)
