I also have the kernel boot parameter aerdriver.forceload=y
With this config, I see that the relevant devices appear to support Advanced Error Reporting (visible in lspci -v output).
However, when I attempt to inject errors to them the injections fail for various reasons. None of them (out of about a dozen candidate devices) succeeds. The aer_inject facility is currently the only means I have of testing this functionality. Note that on the same hardware with a RHEL-6 based (2.6.32) kernel, the injections work correctly. I need to make them also work with 5.5.
Before I go and track down those various errors, I want to verify that I have the right kernel and that it's configured correctly. The required code seems to be present in the kernel. I suspect there's something going wrong during driver initialization and device probing.
Once again, I need answers to these two specific questions:
1) Is PCIe Advanced Error Reporting (including error injections) known to work in 5.5?
2) What configuration options do I need to select in order to enable it?
