Hi,
I'm trying to get pci-express hotplug working in a box here. I don't
really care about the hotplug aspect, I just want the darn pci-e slots
that are designated hotplug slots to actually WORK. When I load pciehp,
I get:
Firmware did not grant requested _OSC control

pciehp 0000:80:09.0:pcie04: service driver pciehp loaded
pciehp: PCI Express Hot Plug Controller Driver version: 0.4
and the devices in the hotplug slots stay off. Is this an ACPI/bios
issue? How can I debug this?
