Created attachment 257169 [details] kernel config In dmesg, I see tons of these messages: [ 261.754916] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 261.754927] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 261.754935] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 261.754940] pcieport 0000:00:1d.0: [12] Replay Timer Timeout [ 285.146589] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 285.146604] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 285.146616] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 285.146623] pcieport 0000:00:1d.0: [12] Replay Timer Timeout ... they are repeated many many times, in particular if disk I/O occurs.

I do not know whether I should worry, for example. I do not know what this replay timer means, but might this have something to do with putting the SSD in sleep mode? Can the replay timer timeout be increased somehow, maybe? Is my SSD overheating maybe? The System is a Dell XPS 9560 (Kaby Lake). The kernel config is attached. I have the following kernel parameters set, to be able to use bumblebee: pcie_port_pm=off acpi_rev_override
The obvious workaround is to be ignorant and disable AER altogether via pci=noaer
Hi All, I got the same problem on a the (almost) same laptop (Dell Precision 5520). We could indeed disable aer, buts thats not a FIX ofcourse :) I receive the following messages on a 4.15-rc4 (drm-tip) kernel: [ 136.777360] pcieport 0000:00:1d.0: AER: Multiple Corrected error received: id=00e8 [ 136.777392] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 136.777396] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 136.777398] pcieport 0000:00:1d.0: [12] Replay Timer Timeout [ 136.777399] pcieport 0000:00:1d.0: Error of this Agent(00e8) is reported first [ 136.777403] nvme 0000:04:00.0: PCIe Bus Error: severity=Corrected, type=Physical Layer, id=0400(Receiver ID) [ 136.777404] nvme 0000:04:00.0: device [1c5c:1284] error status/mask=00000081/0000e000 [ 136.777405] nvme 0000:04:00.0: [ 0] Receiver Error (First) [ 136.777406] nvme 0000:04:00.0: [ 7] Bad DLLP [ 228.424502] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 228.424514] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 228.424519] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 228.424522] pcieport 0000:00:1d.0: [12] Replay Timer Timeout [ 901.426214] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 901.426227] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 901.426234] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 901.426238] pcieport 0000:00:1d.0: [12] Replay Timer Timeout [ 1378.607349] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 1378.607356] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 1378.607360] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 1378.607362] pcieport 0000:00:1d.0: [12] Replay Timer Timeout [ 1391.919513] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 1391.919526] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 1391.919532] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 1391.919537] pcieport 0000:00:1d.0: [12] Replay Timer Timeout [ 1604.654186] pcieport 0000:00:1d.0: AER: Corrected error received: id=00e8 [ 1604.654200] pcieport 0000:00:1d.0: PCIe Bus Error: severity=Corrected, type=Data Link Layer, id=00e8(Transmitter ID) [ 1604.654209] pcieport 0000:00:1d.0: device [8086:a118] error status/mask=00001000/00002000 [ 1604.654215] pcieport 0000:00:1d.0: [12] Replay Timer Timeout I hope this can be pinpointed and fixed! Please let me know if additional information is needed! Thanks Jean-Louis
The Arch Linux Wiki suggests the following workaround: pci=nommconf I haven't seen the error since I am using this option. https://wiki.archlinux.org/index.php/Dell_XPS_15_9560
Same laptop (Dell XPS 9560) now running Linux 5.5.9. Unless I am using pci=nommconf, I still get the AER errors. What is going on? Shouldn't the Dell XPS 9560 be added to some sort of blacklist, maybe? Do I really need to use pci=nommconf or is there some other workaround that has less sideeffects? Any help appreciated.
Hi Sven, > Do I really need to use pci=nommconf or is there some other workaround that > has less sideeffects? according to https://bbs.archlinux.org/viewtopic.php?id=233230, one could use pci=noaer to just disable AER: "it seems disabling AER should be safe, and you are still left with basic PCIe error reporting capabilities. AER is just for "advanced" error reporting."
Those errors may be related to Dell laptops because I have the same error with: Laptop Dell Inspiron 15 5570 i7-8550U
