When it does happen, I can see from dmesg that the messages keep coming, many each second.
The two suggestions I've seen for this are to pass 'pci=noaer' as a kernel boot option, just to switch the messages off (the reasoning being there is no actual fault); or pci=nommconf, see the first answer here:
https://unix.stackexchange.com/question ... er-bad-tlp
But I've no idea whether there might be a hardware fault, something wrong with firmware, or something else.
This started within the past few days, so could be related to the latest kernel update.
