I tried the new patch made by Zhang Rui, and there is a problem, I can not compile the kernel 4.6.1 with this patch, I get an error related to quirks.c file : drivers/pci/quirks.c:1586:189: error: ‘PCI_ANY’ undeclared here (not in a function) gcc doesn't know what is "PCI_ANY", this patch seems incomplete and needs some modifications : commit 09981db5b0c9a6865aa39126b71bc87718577e4b Author: Zhang Rui <rui.zhang@xxxxxxxxx> Date: Mon Aug 24 15:27:11 2015 -0500 PCI: Disable async suspend/resume for JMicron multi-function SATA/AHCI On multi-function JMicron SATA/PATA/AHCI devices, the PATA controller at function 1 doesn't work if it is powered on before the SATA controller at function 0. The result is that PATA doesn't work after resume, and messages like this: pata_jmicron 0000:02:00.1: Refused to change power state, currently in D3 irq 17: nobody cared (try booting with the "irqpoll" option) e6b7e41cdd8c ("ata: Disabling the async PM for JMicron chip 363/361") solved this problem for JMicron 361 and 363 devices. With async suspend disabled, we always power on function 0 before function 1. Barto then reported the same problem with a JMicron 368 (see comment #57 in the bugzilla). Rather than extending the blacklist piecemeal, disable async suspend for all JMicron multi-function SATA/PATA/AHCI devices. This quirk could stay in the ahci and pata_jmicron drivers, but it's likely the problem will occur even if pata_jmicron isn't loaded until after the suspend/resume. Making it a PCI quirk ensures that we'll preserve the power-on order even if the drivers aren't loaded.
