We recently obtained a new a Lenovo Edge 0578-CTO. The r8169 driver causes instability in the system on this machine. The problem is that in rtl8169_rx_interrupt (status & 0x00001FFF) returns values less than four on this machine. This results in this line:

int pkt_size = (status & 0x00001FFF) - 4;

giving a huge packet size which causes problem when the packet is copied. For a work around we've added a patch to drop packets when we see this condition. I have attached lspci -vvv for this device and a patch for the work around we're using.
