My update (after a reboot caused by a crashed hibernation attempt at uptime ~8 days):

There have been TWO changes since I last had problems:
1. pcie_aspm=off
2. re-seating the iwlwifi mini-pci card in its socket
I am starting to believe I am in the clear here, but I am not yet convinced
since the root cause is still unknown. In any case, thanks for all of you for
helping hunt this down.
Dafydd: I think you might want to try pcie_asmp=off next
Cheers,
Juha
