Running Ubuntu 17.10 (upgraded from Gnome Ubuntu recently) $lsb_release -rd Description: Ubuntu 17.10 Release: 17.10 I observed that five~ error messages like these popup from time to time in dmesg: [ 6000.482060] pcieport 0000:00:1c.4: AER: Corrected error received: id=00e4 [ 6000.482082] pcieport 0000:00:1c.4: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e4(Transmitter ID) [ 6000.482095] pcieport 0000:00:1c.4: device [8086:9d14] error status/mask=00001000/00002000 [ 6000.482105] pcieport 0000:00:1c.4: [12] Replay Timer Timeout A similar report exists for errors like this: 1521173 but not sure if it is related to the wifi problem. Most commenters in that report runs Realtek Wifi adapters while I have ath. Removing and adding the ath_pci module or disabling and enabling wifi with network manager seems to fix the issue for a while: $ sudo modprobe -r ath10k_pci $ sudo modprobe ath10k_pci ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: linux-image-4.13.0-32-generic 4.13.0-32.35 ProcVersionSignature: Ubuntu 4.13.0-32.35-generic 4.13.13 Uname: Linux 4.13.0-32-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: niklas 3554 F.... pulseaudio CurrentDesktop: GNOME Date: Sat Jan 27 12:11:31 2018 HibernationDevice: RESUME=UUID=5eda62e7-dbb8-402c-b33b-311c418b4f78 InstallationDate: Installed on 2017-09-27 (121 days ago) InstallationMedia: Ubuntu-GNOME 17.04 "Zesty Zapus" - Release amd64 (20170412) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 0c45:670c Microdia Bus 001 Device 003: ID 04f3:2234 Elan Microelectronics Corp.
