AER reporting on NVME board

AER reporting on NVME board

[Yogi Wannabe]

Hi,

I'm running Ubuntu 16.10 desktop with Kernel 4.8.0-22-generic. I'm
trying to enable PCI AER reporting.

/boot/config-`uname -r` shows

CONFIG_ACPI_APEI_PCIEAER=y
CONFIG_PCIAER=y
CONFIG_PCIEPORTBUS=y

so clearly AER reporting has been enabled. Yet in dmesg I see this:

acpi PNP0A08: _OSC: platform does not support [AER]

I have tried this on several systems with different SuperMicro
motherboards and I see the same message. I don't see any BIOS settings
for AER configuration.

I know this is not a NVME driver issue, but I have not been able to
resolve this even after posting to other forums so I'm hoping some
here can point me in the right direction.

TIA

AER support is provided by PCIe root ports, and the message is telling
you your platform doesn't have your desired capabilities.
