Use "uname -a" to get the current kernel version, architecture.

That's unfortunate, but it might have just been a transient problem.
The log has a pile of these AER errors:

[  283.723848] pcieport 0000:00:1c.5: AER: PCIe Bus Error:
severity=Corrected, type=Data Link Layer, (Transmitter ID)
[  283.723855] pcieport 0000:00:1c.5: AER:   device [8086:9d15] error
status/mask=00001000/00002000
[  283.723859] pcieport 0000:00:1c.5: AER:    [12] Timeout

Which looks like a root port is getting a timeouts while trying to
talk to its downstream device. It's hard to say anything more without
knowing what the downstream device is, or what the system is. If this
is a laptop it might be due to buggy power management, but it might
just be flakey hardware.

Can you provide the full dmesg and the output of lspci -vv?
