Hello,
I tried adding those two patches, but I still see this splat shortly after starting
my test. The kernel I am using is here:
https://github.com/greearb/linux-ct-4.13
I've seen similar issues at least back to the 4.0 kernel, including stock kernels and my
own kernels with additional patches.

Kernel driver in use: e1000e
Kernel modules: e1000e
My test is a (custom) traffic generator that is setting up 30k tcp connections
between two e1000e ports and sending traffic as fast as possible.
I'd be happy to help you set up this exact tool on your system(s),
but we have seen similar issues with e1000e in other high-speed tests, so I don't think it
is specific to this particular test. Maybe this test makes it easier to reproduce
however.
Thanks,
Ben

Hello,
I tried adding those two patches, but I still see this splat shortly after starting
my test. The kernel I am using is here:
https://github.com/greearb/linux-ct-4.13
I've seen similar issues at least back to the 4.0 kernel, including stock kernels and my
own kernels with additional patches.

Capabilities: [140 v1] Device Serial Number 00-25-90-ff-ff-d2-06-aa
Kernel driver in use: e1000e
Kernel modules: e1000e
My test is a (custom) traffic generator that is setting up 30k tcp connections
between two e1000e ports and sending traffic as fast as possible.
I'd be happy to help you set up this exact tool on your system(s),
but we have seen similar issues with e1000e in other high-speed tests, so I don't think it
is specific to this particular test. Maybe this test makes it easier to reproduce
however.
Thanks,
Ben
