My network Dell laptop WiFi connection started failing suddenly, and I found the following messages in dmesg
not sure if related, I can't find the device id with lspci
. How can I find it, and should I be worried hardware is broken?
[260319.955706] pcieport 0000:00:1c.4: AER: PCIe Bus Error: severity=Corrected, type=Data Link Layer, (Transmitter ID)

[260319.955724] pcieport 0000:00:1c.4: AER: [12] Timeout
lspci
shows the device is the WiFi card. This was not happening with 16.04, but the sound was not working. With 20.04 fully updated + BIOS update the sound works but I'm getting this error all the time.
