Re: [E1000-devel] rx_no_dma_resources - Issue on newer hardware (not on older hardware)

Scott be sure to try running turbostat on both old and new servers as I suspect the 50us wake latency of C6 power state may cause drops. The new kernels enable deeper sleep. You can also try a bios setting to disable deep sleep states, leave on C1 only. There was a program called cpudmalaten

We have three generations of servers running nearly identical software. Each subscribes to a variety of multicast groups taking in, on average, 200-300Mbps of data. The oldest generation (2x Xeon X5670, SuperMicro 6016T-NTRF, Intel X520-DA2) has no issues handling all the incoming data. (zero rx_n
