Hi Eric, I found the same 5755m NIC as yours but I couldn't duplicate any problems. I ran netperf in a loop and it was running fine. Here's my device and it should be identical to yours: tg3.c:v3.123 (March 21, 2012) tg3 0000:20:00.0: eth0: Tigon3 [partno(BCM95755m) rev a002] (PCI Express) MAC address 00:10:18:00:00:00 tg3 0000:20:00.0: eth0: attached PHY is 5755 (10/100/1000Base-T Ethernet) (WireSpeed[1], EEE[0]) tg3 0000:20:00.0: eth0: RXcsums[1] LinkChgREG[0] MIirq[0] ASF[0] TSOcap[1] tg3 0000:20:00.0: eth0: dma_rwctrl[76180000] dma_mask[64-bit]
