This one has the top chopped off it which normally says _why_ it happened. I'm not about to waste my time by guessing... Please provide the _full_ crash log, including the lines which come before "Modules linked in:" And no, pci_iomap is not asynchronous. That'd just be damned stupid and would break virtually all drivers.
