ACPI _OSC control
- by nmc
I've noticed an error from dmesg output that ubuntu canot enable ASPM:
[ 0.192722] pci0000:00: ACPI _OSC support notification failed, disabling PCIe ASPM
[ 0.192728] pci0000:00: Unable to request _OSC control (_OSC support mask: 0x08)
While I know that this is not a bug, I'd like to ask if there is a way to correct it and enable ASPM, the reason being that it should increase battery life (powertop shows that PCIe is always 100% on).
Edit: I am running on an ASUS eee pc 1015px with the latest bios version (1401)
