Ilari (ilarinews), it will help immensely if you filed a new report with the
Ubuntu repository kernel (not mainline/upstream) via a terminal:

I have same issue. Ubuntu 16.04 64bit.
Atheros AR8121/AR8113/AR8114 1Gbps
Controller is integrated PCI-e on morherboard P5QL Pro.
Throughput is about 2Mbps.
I have tested also with 100Mbps USB network adapter, 3Com 100Mbps, different
cable, all other work fine, throughput ~10Mbps.

Hi! sorry for the delay, I ended up putting an Intel NIC in so I could
get the machine back to production and then work got me busy. I should
be able to test the kernel out later this week. Thanks for your hard
work and patience.

I built a Vivid test kernel with the CONFIG_COMMON_CLK_QCOM config
option disabled.
The kernel can be downloaded from:

Can you test this kernel and see if it exhibits the bug?
Note, with this kernel you need to install both the linux-image and
I haven't been able to get the bisect to continue yet. But looking at the code
and changes, the regression could be due to:
085d7a4 clk: qcom: Add a regmap type clock struct
It was added in v3.14-rc1. I'll investigate further.

Bugs,
I started a bisect between 3.13 final an d3.14-rc1. The first kernel is
up to commit:
365c483f190fea03971b3eca8d68406f425777b5
The kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1453391/
Can you test this kernel and see if it exhibits the bug. I'll build the
next kernel
(botched video resolved - linux-headers-generic package was missing)

Hi, without any assistance this is the best I could come up with for a bisect
log.
I've tried asking for help on #ubuntu and #ubuntu-kernel with no success.
The driver in linux kernel Ubuntu-3.13 works and Ubuntu-3.19 does not.
Please advise on what I can do next to help.
** Attachment
We should next test some of the 3.14 release candidates to see which one
introduced the bug. Can you test the following:
3.14-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc1-trusty/
3.14-rc4: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc4-trusty/
3.14-rc7:
No such luck. Here are the results:
Linux Main-PC 3.14.0-031400rc1-generic #201402022035 SMP Mon Feb 3 01:37:33 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.
Can you test the following kernels and post back? We are looking for the
first kernel
Thank you so much, Joseph, for agreeing to help.
These all seem bad. Please find the results:
Linux Main-PC 3.14.0-031400-generic #201403310035 SMP Mon Mar 31 04:36:23 UTC

Linux Main-PC 3.16.0-031600-generic #201408031935 SMP
Thanks for testing. We should be able to bisect between the v3.13 final
kernel and v3.14-rc1. Can you test the 3.13 final kernel, just to
confirm it does not exhibit the bug? It can be downloaded from:

The instructions are not so easy to follow on how to fully bisect the
kernel. Can someone walk me through the process.
This is as far as I got what next?

Cyking, the next step is to fully commit bisect from kernel 3.13 to 3.19
in order to identify the last good kernel commit, followed immediately
by the first bad one. This will allow for a more expedited analysis of
the root cause of your issue. Could you please do this following
Cyking, thank you for reporting this and helping make Ubuntu better.
