@Kevin (thenewmanium). I honestly think this is a Intel driver bug. See my thread here on the Intel forums.
https://forums.intel.com/s/question/0D50P00004CK4wZSAT/intel-x550-not- negotiating-to-10gb-on-x299-chipset?language=en_US Their conclusion was that it was an Asus changed x550 chip. Asus said they won't fix it because they "don't support linux". Intel told me they won't do anything because Asus borked with the firmware. I'm basically stuck in the middle of two vendors not wanting to do anything because one doesn't support it and the other doesn't want to look at it because the other vendor changed it. If you can validate that its the same issue with different hardware, it might get some traction (fingers crossed). -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1812410 Title: Intel x550 not negotiating to 10Gb on x299 chipset Status in linux package in Ubuntu: Confirmed Bug description: I am having an issue with this particular machine auto negotiating 10Gb. The onboard LOM will only negotiate to 1Gb. If I run `ethtool -s <device> advertise 0x1000`, the machine will delink and then negotiate to 10Gb and work as expecting. Rebooting the machine (or unplugging network cable) will cause it to negotiate to 1G again resulting in having to run the ethtool command again. This is what I have tried: Tried different cable from confirmed working machine that auto negotiates to 10Gb. Tried upgrading ixgbe driver to latest (5.5.3) Tried upgrading X550 firmware. I put an Intel x540-T1 card in the machine and that card works properly and negotiates to 10Gb automatically. Move the cable to the LOM x550, and it still negotiates to 1Gb. I also tried loading a live version of Fedora 29 (Kernel 4.18) with same exact symptoms. We have several other machine negotiating fine on the same exact switch. I have tried those cables to test this problematic machine with same result as above. We have a machine that is pretty similar in hardware that is not exhibiting this issue. It is an ASUS x99 motherboard, with the same LOM Intel x550 card, running on 16.04. The machine that is causing problems is an Asus x299 motherboard with the Intel x550 LOM card running 18.04 (16.04 won't work on the x299 chipset for some reason). I have a suspicion that it could potentially be related to the x299? The only way I have been able to get this problematic machine to negotiate to 10Gbps automatically is by plugging a cable directly from the LOM x550 of the problematic machine to another machines 10Gb network card. Doing that, the problematic machine will negotiate properly to 10Gb. I'm trying to find another 10Gb switch to test with to see if it could be unique to this combination of switch and machine. However, I'm reluctant to blame it on the switch since we have about several other machine working perfectly fine on the switch (some with the same exact x550 LOM).
