Dell Inspiron P74G, Kubuntu 19.04 Disco, kernel 5.0.0-13-generic. I'm affected as well by this bug, with ~50 lines per minute of errors in the syslog.
I noticed only recently the issue on my Kubuntu 18.04 LTS setup (say, this October 2019). Since then I upgraded to 19.04, but with no improvement. My errors in dmesg are of the same form as stated above, with two recurring types of error statuses: pcieport 0000:00:1c.4: AER: Corrected error received: 0000:00:1c.4 pcieport 0000:00:1c.4: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Transmitter ID) pcieport 0000:00:1c.4: device [8086:9d14] error status/mask=00001000/00002000 pcieport 0000:00:1c.4: [12] Timeout pcieport 0000:00:1c.4: AER: Corrected error received: 0000:00:1c.4 pcieport 0000:00:1c.4: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Transmitter ID) pcieport 0000:00:1c.4: device [8086:9d14] error status/mask=00003000/00002000 pcieport 0000:00:1c.4: [12] Timeout That pcie port is shown to be connected to the Atheros WiFi of the laptop: +-1c.4-[02]----00.0 Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter The output of lshw for it is: *-pci:1 description: PCI bridge product: Sunrise Point-LP PCI Express Root Port #5 vendor: Intel Corporation physical id: 1c.4 bus info: pci@0000:00:1c.4 version: f1 width: 32 bits clock: 33MHz capabilities: pci pciexpress msi pm normal_decode bus_master cap_list configuration: driver=pcieport resources: irq:123 memory:d5000000-d51fffff *-network description: Wireless interface product: QCA6174 802.11ac Wireless Network Adapter vendor: Qualcomm Atheros physical id: 0 bus info: pci@0000:02:00.0 logical name: wlp2s0 version: 32 serial: [edited for privacy] width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list ethernet physical wireless configuration: broadcast=yes driver=ath10k_pci driverversion=5.0.0-13-generic firmware=RM.4.4.1.c2-00057-QCARMSWP-1 ip=192.168.0.71 latency=0 link=yes multicast=yes wireless=IEEE 802.11 resources: irq:131 memory:d5000000-d51fffff I cannot find an APSM disable option in my BIOS setup. A guy named Dennis E. Mungai digged into the issue last year (link below), and his temporary fix (turning off the report bit for AER Corrected errors) worked for me, without the need to turn off AER for the whole system. https://gist.github.com/Brainiarc7/3179144393747f35e5155fdbfd675554 I find interesting that for most of us this issue affects laptop WiFi cards from different vendors. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1521173 Title: AER: Corrected error received: id=00e0 Status in Linux: Unknown Status in linux package in Ubuntu: Triaged Status in linux source package in Xenial: Triaged Bug description: WORKAROUND: add pci=noaer to your kernel command line: 1) edit /etc/default/grub and and add pci=noaer to the line starting with GRUB_CMDLINE_LINUX_DEFAULT.
