The GPE fires and the xHCI host controller comes out of D3 after a stream of: Sep 30 17:07:32 talon kernel: [ 197.745312] ehci_hcd 0000:00:1d.0: pci_acpi_wake_dev Sep 30 17:07:32 talon kernel: [ 197.745321] ehci_hcd 0000:00:1a.0: pci_acpi_wake_dev Sep 30 17:07:32 talon kernel: [ 197.745326] snd_hda_intel 0000:00:1b.0: pci_acpi_wake_dev Sep 30 17:07:32 talon kernel: [ 197.745331] e1000e 0000:00:19.0: pci_acpi_wake_dev It does seem to take less time to come out of D3 than the previous patch though. I occasionally do not see the host controller come out of D3 when I plug in a new device, but the interrupt count for GPE 0D doesn't increment when that happens, so it's probably just a BIOS or hardware bug. Did mention this was bleeding edge hardware?
