Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.8 kernel[0] (Not a kernel in the daily directory) and install both the linux-image and linux-image-extra .deb packages.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report[0]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

Please follow the instructions on the wiki page[0]. The first step is to email the appropriate mailing list. If no response is received, then a bug may be opened on bugzilla.kernel.org.

May be related to bug 1134289

[Igor Gnatenko (i-gnatenko-brain)]

bug 1134289. yes.

[Joseph Salisbury (jsalisbury)]

In addition to reporting this issue upstream, I'd like to start a kernel bisect to identify the commit that introduced this regression. Would you also be able to help in a bisect? It will require testing 10 to 12 kernels.

[Igor Gnatenko (i-gnatenko-brain)]

yes.
In the upstream, I can write tonight ...

[Mr.Gosh (mr-gosh)]

This bug also affects my Thinkpad x220t

[Mr.Gosh (mr-gosh)]

I tested the Release Candidate Kernels and recognized that the Bug first appeared in RC4 of Kernel 3.8.0 - so with Kernel 3.8.0 RC3 the wired network worked after Resume on my Thinkpad x220t...

[Joseph Salisbury (jsalisbury)]

I started a kernel bisect between v3.8-rc3 final and v3.8-rc4. The kernel bisect will require testing of about 7-10 test kernels.

I built the first test kernel, up to the following commit:
46fed0a57cd2b1022b556394ef586632a5b2e4e7

The test kernel can be downloaded from:
http://people.canonical.com/~jsalisbury/lp1131616

Can you test that kernel and report back if it has the bug or not. I will build the next test kernel based on your test results.

Thanks in advance

[Igor Gnatenko (i-gnatenko-brain)]

suspend not work..
ethernet not working after "suspend" before AC plug

[Mr.Gosh (mr-gosh)]

Is this as an information enough - or do we need to do more than this?

[Mr.Gosh (mr-gosh)]

The Bug is still present with the newest Kernel update:
Linux goshbook 3.8.0-9-generic #18-Ubuntu SMP Thu Feb 28 17:02:06 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Funny fact: If you replug the AC Adapter, the network gets connected. After unplugging the AC it keeps connected. Unplugging und replugging the network destroys the connection...

[Igor Gnatenko (i-gnatenko-brain)]

In my thinkpad at update kernel he suspend not work..
He suspend, but not exit suspend

[Igor Gnatenko (i-gnatenko-brain)]

In 3.8.0-10 notebook not boot... :( (purple screen)
In 3.8.2-raring notebook not boot too... :( (purple screen)

[Joseph Salisbury (jsalisbury)]

@Brain, per comment #17, it sounds like my test kernel posted in #16 still contains the bug? If that is correct, I will update the bisect and build the next test kernel.

@Mr.Gosh, would it also be possible for you to test the kernel posted in comment #16?

[Igor Gnatenko (i-gnatenko-brain)]

@Joseph Salisbury, yes.
p.s. In 3.8.0-10 and later my ThinkPad not boot... :(

[Joseph Salisbury (jsalisbury)]

I built the next test kernel, which is up to the following commit:
7c8284c3aa127ffe72a90a1bad52183ec9ad870a

The test kernel can be downloaded from:
http://people.canonical.com/~jsalisbury/lp1131616

Can you test that kernel and report back if it has the bug or not. I will build the next test kernel based on your test results.

Thanks in advance

[Igor Gnatenko (i-gnatenko-brain)]

yes, I can.
1-2 days.

[Mr.Gosh (mr-gosh)]

In this Test-Kernel the Bug isn't present.

Means I can Sleep & Resume without AC Adapter - and Wired Network works....!

[Mr.Gosh (mr-gosh)]

I installed the Kernel from within the directory directly - because the sub-directory of patch
7c8284c3aa127ffe72a90a1bad52183ec9ad870a
is empty - now I will install the Kernel from Comment #16 to see what this Kernel does with my machine.....

[Igor Gnatenko (i-gnatenko-brain)]

@Joseph Salisbury, In 7c8284c3aa127ffe72a90a1bad52183ec9ad870a bug is present.

[Igor Gnatenko (i-gnatenko-brain)]

@Joseph Salisbury, in 3.8-rc1 this bug is present...

[Igor Gnatenko (i-gnatenko-brain)]

@Joseph Salisbury, i also tested Debian and in 3.2.x and 3.7 liquorix bug is not present

[Igor Gnatenko (i-gnatenko-brain)]

@Joseph Salisbury, i testing Fedora 18:
Linux version 3.8.1-201.fc18.x86_64 (<email address hidden>) (gcc version 4.7.2 20121109 (Red Hat 4.7.2-8) (GCC) ) #1 SMP Thu Feb 28 19:23:08 UTC 2013
bug is not present

[Joseph Salisbury (jsalisbury)]

Comment #26 and #28 seem to contradict each other. Can you confirm you tested the kernel located in the top level directory at:
http://people.canonical.com/~jsalisbury/lp1131616

The kernel .deb file names are:
linux-image-3.8.0-030800rc3-generic_3.8.0-030800rc3.201302281340_amd64.deb
linux-image-extra-3.8.0-030800rc3-generic_3.8.0-030800rc3.201302281340_amd64.deb

You can confirm which kernel is booted by running:
cat /proc/version

[Igor Gnatenko (i-gnatenko-brain)]

I tested kernel on top directory. 7th march..

[Mr.Gosh (mr-gosh)]

I'll repeat the test when I am at home again...

[Mr.Gosh (mr-gosh)]

OK, I'm very sorry!
In this Kernel the bug is also present:
Linux version 3.8.0-030800rc3-generic (jsalisbury@gomeisa) (gcc version 4.7.2 (Ubuntu/Linaro 4.7.2-2ubuntu1) ) #201302281340 SMP Thu Feb 28 18:40:51 UTC 2013

Thanks for testing.

[Mr.Gosh (mr-gosh)]

The Bug is till Present.
Now I know why I thought it isn't during the last Test. The Connections doesn't get Lost if you unplug AC. If you unplug Network and replug it - it doesn't get reconnected...

So - The Bug is still Present...

Hey I tested this Kernel and it works.
I can sleep and resume - unplug and replug ethernet and the cable is recognized and a dhcp server ist connected.

uname -a gives me:

jsalisbury, mr-gosh:
Sorry, I can't test this bug. I using Fedora.
P.S. In Fedora all works!

[Raid (pdecarlos)]

Same problem in a HP 2530p upgraded from 12.10 to 13.04 final 3.8.0-19-generic x86_64 (eth0 don't works without AC).

I've tested linux-image-3.8.0-030800rc2-generic_3.8.0-030800rc2.201304241225_amd64 and the wired network works without AC.

I don't see your new test-kernel - is this really allready uploaded?

[Joseph Salisbury (jsalisbury)]

This could be similar to bug 1165248 and bug 1169244

Can you test the v3.9-rc2 kernel and report back if it exhibits this bug?

v3.9-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9-rc2-raring/

[Joseph Salisbury (jsalisbury)]

I built a Raring test kernel with commit 66148ba applied.

The test kernel can be downloaded from:
http://kernel.ubuntu.com/~jsalisbury/lp1112652

Can you test that kernel and report back if it has the bug or not.

One thing to note, you will need to install both the linux-image and linux-image-extra .deb packages.

Thanks in advance!

[Mr.Gosh (mr-gosh)]

The Bug is present in:

should i test 3.9-rc2 anyway?
