Probably a bit under that, but yes a few minutes, but that's with the 128 PCI latency; with the 32 it would do it in seconds. > The e100 NIC port that fails is just receiving data > from the camera correct? Well it's a PC just sitting there with a browser looking at the camera > From that stats something is doing an awful lot > of transmitting. An order of magnitude more if I read this correctly. > What is it transmitting? Am I understanding of this correct? if so > can you please tell me what's going on with all the transmits? It doesn't seem a lot; this was extracted by grepping for tx_bytes in that log; each line is one minute rx_bytes bytes/min bytes/sec 243797360 0 0 243797360 0 0 243799556 2196 36.6 243799736 180 3 243802072 2336 38.9333 243802072 0 0 244921827 1119755 18662.6 251741140 6819313 113655 < A 258691588 6950448 115841 265594929 6903341 115056 276003297 10408368 173473 302321897 26318600 438643 < B 328971818 26649921 444165 355240830 26269012 437817 381531716 26290886 438181 407800668 26268952 437816 434062530 26261862 437698 460339412 26276882 437948 486653710 26314298 438572 507377956 20724246 345404 507377956 0 0 507382596 4640 77.3333 So I suspect at A I started it going, at B probably increased the frame rate; the camera is doing JPEG images, at about 15 fps max, so 430KB/15 ~ 30KByte/image which is reasonable for a 640x480 image. > Also, have you tried a different e100 NIC?

I was running a plain e100 single NIC I think without trouble (although I'd have to check what was plugged into it), this is the only dual card I've got. Personally I was guessing it was related to the bridge arrangement which is why I guessed at PCI latency in the 1st place - but that's a straight guess.
