Package: src:linux
Version: 3.16.7-ckt11-1+deb8u3
Severity: important

Hi,

I'm encountering an issue with the current jessie kernel on a Dell
Optiplex 9020 equipped with a
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-LM (rev 
04)

The NIC hangs under some conditions. Those conditions are not completely
clear: it occurs when downloading packages from this machine to several
(5) machines, but I couldn't trigger it using simple nuttcp data
transfers).

I've confirmed that the backports kernel (4.1.3-1~bpo8+1) is _not_
affected.

Dmesg output during the hangs:

There's another mention of this problem at
https://communities.intel.com/thread/70244, but the solution suggested
there (switch to Intel's version of e1000e) is not suitable for me.

I went through the kernel git logs for e1000e at
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/net/ethernet/intel/e1000e
but I couldn't find anything extremely relevant.
