Eric Carlier, thank you for reporting this and helping make Ubuntu
better. Could you please test the latest upstream kernel available from
the very top line at the top of the page (the release names are
irrelevant for testing, and please do not test the daily folder)
following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow
additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into
the OS) please make a comment in your report about this, and continue to test
the next most recent kernel version until you can test to the issue. Once
you've tested the upstream kernel, please comment on which kernel version
specifically you tested. If this bug is fixed in the mainline kernel, please
add the following tags by clicking on the yellow circle with a black pencil
icon, next to the word Tags, located at the bottom of the report description:
kernel-fixed-upstream
kernel-fixed-upstream-X.Y-rcZ
Where XY and Z are numbers corresponding to the kernel version.
If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-X.Y-rcZ
Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results.
Thank you for your understanding.

Title:
interface eth0 disappears after network cable unplug/re-plug
Status in linux package in Ubuntu:
Incomplete
Bug description:
The following bug is reproducible with linux-image-3.13.0-53-generic,
but not with linux-image-3.13.0-52-generic.
When I unplug the Ethernet cable from my laptop, I get the following messages
in /var/log/kern.log after a few seconds (~20s):
May 22 13:59:36 host kernel: [ 5498.465626] pciehp 0000:00:1c.5:pcie04: Card

machine can't be idle since disabled for 10ms second
Then, when I re-plug the cable, eth0 does not appear in network manager;
there is no message in kern.log.
eth0 does not appear in ifconfig -a
$ ifconfig -a

I tried to reinitialize networking with the following:
sudo modprobe -r atl1c
sudo modprobe atl1c
Still no eth0 and no message in kern.log
I tried
$ sudo ifup eth0
Ignoring unknown interface eth0=eth0.
Same symptoms occur when I reboot my router, and its Ethernet
interface becomes temporarily unavailable.
Only way I found to restore eth0 was rebooting.
