Description of problem:
When using the wired Ethernet network connection on my rtl8111/8168/8411 ethernet, the connection will randomly drop.  When I check the interface with ifconfig, it shows that it still has an ip address, etc.

The connection comes back when I disable and renable it in Network Manager, but only momentarily.

Version-Release number of selected component (if applicable):
Fedora 23

How reproducible:
Every time

Steps to Reproduce:
1. Boot into Fedora 23 with rtl8111/8168/8411 ethernet device
2. Start to use network

Actual results:
Being able to communicate with other devices on internet and local network

Expected results:
No such communication

Additional info:
It looks like there are a number of other bugs with this device from older versions of Fedora.

Let me know if you need me to run any output from my computer

Some more information.  I stopped NetworkManager and still had the issue.  Had to do an ifconfig down then up to get it to work again, but it only worked temporarily.

I downloaded the rpms for the rawhide kernel, and that didn't correct anything either.
Comment 2 Christian Stadelmann 2015-11-26 14:21:27 EST
Same here, same hardware. Happens especially often on suspend+resume, but not limited to that. Sometimes the kernel seems to recover itself after some 10…30 seconds, sometimes it doesn't. Happens ca. once per 10 hours running fedora and ca. each second time I suspend (to ram). This is no recent regression but has been there for about 3 months.

# rmmod r8169
# modprobe r8169
helps as a workaround too.

In dmesg I see this error message, can you confirm seeing it?

ACPI: \_SB_.PCI0.SBRG.ASOC: Device cannot be configured due to a frequency mismatch

Nothing of obvious interest there in dmesg and journal except from this line.

I am running a 4.2.6-300.fc23.x86_64 kernel.

Comment 3 verslyap 2015-12-06 20:26:05 EST
I was able to get regular ethernet service without it dropping out.  The issue is probably the result of a bug in the linux kernel, as other OSes work fine, but it's probably a result as another piece of hardware on my network.

I use a dd-wrt v24sp2 router configured as a client bridge.  This is the most recent version of dd-wrt that my router can run, but it has a known issue where it doesn't forward multicasts.  When I did a workaround for this issue, this nic doesn't drop it's connect at random anymore.

Now, my NAS and windows box worked just fine when connected to the bridge, so I think Fedora 23 isn't handling something correctly, but it may be the result of this other issue.
Comment 4 Christian Stadelmann 2015-12-07 10:37:27 EST
I don't have a dd-wrt but an AVM Fritz!Box with its latest software available. Both share some code basis.

The AVM Fritz!OS has not recently been updated. It looks like this is an issue specific to the linux kernel. I have rarely seen this issue for months but very often only since some weeks. Looking at https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/drivers/net/ethernet/realtek/r8169.c there some recent changes to the kernel module.

There has been a sleep-related code fix some weeks ago: https://bugzilla.kernel.org/show_bug.cgi?id=104031

Maybe you could try to bisect. I can't do that right now.

Probably a duplicate of bug #1312006
