How do you tell that, about igb? looking at the server I have the igb device on, it doesn't seem to say anything about that ... # vmstat -i interrupt total rate irq1: atkbd0 162 0 irq30: twa0 402647215 187 cpu0: timer 4284778818 1999 irq256: igb0 1282945461 598 irq257: igb0 215507100 100 irq258: igb0 417702261 194 irq259: igb0 314601966 146 irq260: igb0 568062067 265 irq261: igb0 3 0 cpu5: timer 4284744445 1999 cpu6: timer 4284731466 1999 cpu7: timer 4284724508 1999 cpu1: timer 4284893874 1999 cpu3: timer 4284899807 1999 cpu2: timer 4284892325 1999 cpu4: timer 4284897264 1999 Total 37480028742 17493 The server(s) that I am experiencing the hangs on, vmstat -i shows: # vmstat -i interrupt total rate irq1: atkbd0 2 0 irq3: sio1 8 0 irq25: bge0 4614816 213 irq72: ciss0 1835763 85 cpu0: timer 43113685 1997 cpu1: timer 43116889 1997 Total 92681163 4293 Are any of these similiarly using MSI/MSIX? ---- Marc G.
