I had a very brief look on the crashing function ixgbe_update_stats_count(). The only division there is in the one using adapter->num_queue.
Looking at ixgbe_configure_interrups(), seems that one can happily set it to 0 if number of MSI vectors is 1, as is the case according to your dmesg.
SAITOH Masanobu, could you please have a closer look? I wonder if this could have been introduced around rev. 1.96/1.97/1.98 of dev/pci/ixgbe/ixgbe.c, that's when the code related to this changed.
