This is tx side which seems blocked for more than 6 seconds.

To really test the patch, you need following setup :

machine A with r8169 NIC, patch applied, receiver of pktgen flood.

machine B with any NIC, preferably a not buggy one, doing the pktgen
flood to machine A

If machine A survives, my patch is tested and ok.

If machine B crashes, we have another problem to investigate
