What do those screen shots represent?Are these screenshots taken with/without riser card cable inserted?
=> You can check folder name taken with ubuntu version and the figures name taken with/without riser card inserted.
If kernel versions are same, whether it is 14.04 or 16.04 in the user space shouldn’t matter. Can we ask them for the output of ‘uname –a’ in both cases. Also, it would be good to know which packages (rel-23.2 / 24.2 Etc…) they flashed to get 14.04 and 16.04 respectively.
Does Intel LAN card come up on 14.04 if raiser card is not connected?
=> Ubuntu 14.04, rel-r24.1, but we re-built kernel to disable SSC function:
-> Linux tegra-ubuntu 3.10.96+ #3 SMP PREEMPT Wed Aug 31 15:25:33 CST 2016 aarch64 aarch64 aarch64 GNU/Linux
Ubuntu 16.04, rel-r24.2:
-> Linux tegra-ubuntu 3.10.96-tegra #1 SMP PREEMPT Thu Sep 8 13:48:54 PDT 2016 aarch64 aarch64 aarch64 GNU/Linux
Does this card come up in Gen-2 on 14.04 & 16.04 if raiser card is removed? If yes, I think, as our syseng folks predicted, it is something to do with routing length violations at higher speeds.
=> Yes, it can be boot-up with PEX8732 card when plug in PCIe X4 slot without riser card on Jetson TX1.
