If this reproduces, could you bisect?
Well this looks exactly like the e1000 race that we fixed around the time of the last kernel release. That fix never made it into e100 so it's no surprise that we get a similar crash here. The problem is that if a spurious interrupt comes in between request_irq and netif_poll_enable then you'll get a crash at the next netif_rx_complete. It'd be good if this were reproducible as it would allow us to identify the source of the spurious interrupt, which may well be caused by an unrelated bug somewhere else. In any case, e100 should be prepared to deal with spurious interrupts as e1000 has been fixed to do.
