Bug 1161484

There is a kernel problem in dmesg output in bug 1157217, so let's see what kernel people will find.

[30313.221046] ------------[ cut here ]------------
[30313.221059] WARNING: CPU: 0 PID: 9135 at drivers/base/firmware_class.c:1127 _request_firmware+0x519/0x7f0()
...

Can you try with other kernel versions, too?

Nevertheless, please attach NetworkManager logs here
# journalctl -b -u NetworkManager

and output of 'nmcli device' before and after suspend

journal nm

the log "journal nm" and nmcli here are when gnome network is ok

DEVICE         TYPE      STATE        CONNECTION 
virbr0         bridge    connected    virbr0     
enp1s0f0       ethernet  connected    ccnr       
virbr0-nic     tap       connected    virbr0-nic 
enp0s19f2u2c2  ethernet  unavailable  --         
lo             loopback  unmanaged    --

when connection is lost:

DEVICE         TYPE      STATE        CONNECTION
virbr0         bridge    connected    virbr0
enp1s0f0       ethernet  connected    ccnr
virbr0-nic     tap       connected    virbr0-nic
enp0s19f2u2c2  ethernet  unavailable  --
lo             loopback  unmanaged    --

journal nm con lost

also, from gnome bash can ping but cannot do anything else, firewalled restart does not help

another thing is that my connection, when I down it:
# nmcli c down mycon
fails weirdly reporting completely different device
# nmcli c up my con
Error: Connection activation failed: Connection 'ccnr' is not available on the device enp0s19f2u2c2 at this time.

and according to nmcli c show "enp0s19f2u2c2" is another connection and not a device

workaround this, in my case it's Realtek 10ec:8168
modprobe -r r8169 && (sleep 5; modprobe r8169)
Gnome's notification top bar still sticks "?" to network, but gnome-terminal shell an other apps seems to be back online.

Clean default install of Fedora 21 on two identical systems.

Having the same symptoms on a 01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 0e)

Sometimes top bar sticks "?" to network but connections work anyway.

And from time to time using dhcp I can only ping but can't surf, download, update or anything else only ping, firewalled restart does not help. This is also only a problem on the ethernet connection and switching to a static ip solves the problem. Wifi always works connecting to the same dhcp server.

This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle.
Changing version to '22'.
