Is the version of ixgbevf 2.14? I don't see this version on e1000.sf.net. It would help if you could describe your environment and the exact versions of the kernel and driver you are using, but it sounds like you may be using an old driver. > When do dmesg, I will get: > ==================================== > Detected Tx Unit Hang > Tx Queue <0> > TDH, TDT <116>, <116> > next_to_use <116> > next_to_clean <116> > tx_buffer_info[next_to_clean] > next_to_watch <(null)> > eop_desc->wb.status <0> > time_stamp <1003dc688> > jiffies <1003f802a> > ==================================== > I'm not sure what does this message mean, what led to >this message? It means that the HW was not able to transmit a packet in a certain amount of time, which is detected as a Tx hang. When that happens the driver will reset the interface in an attempt to recover.
