Bug#941122: linux-image-5.2.0-2-amd64: e1000e is slooow for I219-LM (rev 11)

Kamil Jońca-5
Package: src:linux
Version: 5.2.9-2
Severity: important

Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

   * What led up to the situation?

Trying to use ethernet controler - but it was very slow (single kilobytes/sec)

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
I took driver from  https://github.com/koljah-de/e1000e-dkms-debian/
removed calls to "mmiowb", compiled and installed - and this module works as expected.
Moreover kernel 5.2 from ubuntu also works.


*** End of the template - remove these template lines ***

We have also seen this with the 4.19 kernel in buster.

Might this one be related:
https://bugzilla.redhat.com/show_bug.cgi?id=1627816 ?

What do dmesg and ethtool say on respective link speed?

def4ec6dce39 ("e1000e: PCIm function state support") would be in
5.3-rc1 and above and was not backported. If you test the package from
experimental, is the issue gone?  If you cherry-pick this commit on
top is the issue gone?

Regards,
Salvatore

I tried installing the linux-image-5.3.0-trunk-amd64 package from
experimental on buster but I still experiencing the same issue.

Interestingly linux-image-4.19.0-6-amd64 is working perfectly while
linux-image-5.2.0-0.bpo.3-amd64 does not.

In reply to this post by Kamil Jońca-5
linux-image-5.3.0-0.bpo.2-amd64 seems to be working which is available
via buster-backports.

I tried suspending a laptop and waking it up and no latency is produced
while running a ping against another node on my LAN.
