| It seems you're having interrupt delivery problems or interrupts are
| getting lost.
| rx_missed_errors indicates frames that were dropped due to the e1000
| adapter's fifo getting full and over flowing.
| >rx_no_buffer_count: 310
| >rx_missed_errors: 5865
| rx_no_buffer_count indicates that the driver didn't return buffers to
| the hardware soon enough, but the hardware was able to store the
| packet (at the time of reception) in the fifo to try again.
|
| Both these indicate to me that there is something wrong with
| interrupts. Maybe interrupt sharing
|
| can you possibly try a back to back connection with another linux box
| and run tcpdump on both ends then ping? it will tell us if traffic is
| truely getting out and coming in okay.
Unfortunately, I can't try this week, but can try it early next week.
|
| also please send output of lspci -vv and cat /proc/interrupts
lspci-vv.out is attached. Here is the /proc/interrupts:
