Those last "fake Tx Hang" messages from the driver show that the upper stack is timing out while the driver doesn't think it has anything to do. The stack dump previous to this is most likely the culprit. Since we don't see any ixgbe call's in the trace I wonder what is going on with the rest of the network stack. When do you see this happening, at boot time, heavy traffic loads?
I would also be interested in seeing the device's statics (i.e. ethtool -S), as well as the pci layout (i.e. lspci -vvv). Is there anything prior to this stack dump in the log that would imply something strange is going on?
