How to determine PCIe slot number from dmesg error message?

Question

I have a Linux system that contains several PCIe cards. dmesg indicates that one of the cards is generating an error:

[ 3970.385387] pcieport 0000:00:02.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=0010(Transmitter ID)
[ 3970.385389] pcieport 0000:00:02.0:   device [8086:2f04] error status/mask=00001000/00002000
[ 3970.385391] pcieport 0000:00:02.0:    [12] Replay Timer Timeout

How can I determine the slot number from [8086:2f04] ?

You can use the following to find information about all slots in the system.

dmidecode -t slot

How can I determine the slot number from [8086:2f04] ?

You can use lspci for that, more specifically lspci -nv. Once you know specifically you can use lspci -s <slot number> to investigate further.
