Subject: Regression of e1000e (I219-LM) from 6.1.90 to 6.6.30

Hi,

<[email protected]> reported on Bugzilla
(https://bugzilla.kernel.org/show_bug.cgi?id=218826) regression on his Thinkpad
T480 with Intel I219-LM:

> After updating from kernel version 6.1.90 to 6.6.30, the e1000e driver exhibits a regression on a Lenovo Thinkpad T480 with an Intel I219-LM Ethernet controller. The system experiences a freeze when an Ethernet cable is plugged in. The issue is not present in the previous kernel version 6.1.90.

> System Information:

Thanks.

Could you try a git bisect between these two kernel versions? You
might be able to limit it to drivers/net/ethernet/intel/e1000e, which
only had around 15 patches.

The BZ reporter (Cc'ed) says that bisection is in progress. You may
want to log in to BZ to reach him.

Thanks.

Bagas, why did you start forwarding these bugs by mail yourself again
after we had agreed you forward them to me, so I can handle it from there?

Yes, you forwarded that particular bug to me a few days ago and I didn't
do anything. But that was on purpose: I usually wait at least two
working days before doing so, as some subsystem are active in bugzilla
and might feel annoyed by starting a separate thread on the mailing list.

Side note: you also apparently make it not obvious enough that you are
just forwarding the bug, as both here and in the other bug your
forwarded today the developer apparently thought it was a bug you face.

Please lets avoid all of that again and switch back to the model we
agreed on a few months ago.

Side note: you should not assume every developer has a BZ account (or is
willing to create one).

Ciao, Thorsten
