Public bug reported:
[Impact]
The APEI (ACPI Platform Error Interface) interface is supposed to report PCIe
errors to the AER (Advanced Error Reporting) driver, which surfaces them to
userspace. However, we're currently only reporting "recoverable" errors and not
errors of other types (e.g. correctable), thus hiding signs of faulty hardware
from the user.
[Test Case]
$ sudo apt install rasdaemon
# On a system that supports ACPI EINJ (dmesg | grep "ACPI: EINJ"), use the
attached script to inject a correctable PCIe error.
$ sudo ras-mc-ctl --errors
# There should be an entry for the injected error, as shown below:
No Memory errors.
PCIe AER events:
1 2018-05-07 17:55:46 +0000 Fatal error: Receiver Error
No Extlog errors.
No MCE errors.
[Regression Risk]
