PCI-Express AER

leave a comment »

Saw this in the dmesg output of one machine:

Firmware did not grant requested _OSC control
aer 0000:00:02.0:pcie02: AER service couldn't init device: no _OSC support

This regards the PCIe AER (Advanced Error Reporting) and ACPI Operating System Capabilities (OSC) features, and it’s nothing you need to worry about (or can do about, for that matter).
