But it somehow doesn't trigger with that same kernel anymore so I'll
consider it a glitch and watch it over the next days.

Ok, I can still see the hardware error message when suspending:

And with 3.8 plus these:
PCI/PM: Clear state_saved during suspend
e1000e: fix pci-device enable-counter balance
e1000e: fix runtime power management transitions
e1000e: fix accessing to suspended device

I sometimes see this:
pci_pm_suspend():e1000_suspend +0x0/0x10 [e1000e] returns -2
dpm_run_callback(): pci_pm_suspend+0x0/0x140 returns -2
PM: Device 0000:00:19.0 failed to suspend async: error -2

Any ideas? Am I missing some patch still?

Try this:
"PCI: Don't try to disable Bus Master on disconnected PCI devices"

But I'm not sure, probably it is unrelated because this code works only (?)
during shutdown/kexec sequences.
