Well, our user that reported the problem first has not responded since I sent him the first kernels needed to bisect the problem. Another our user, however, seems to have a very similar problem: the system cannot wake up the WiFi adapter (Atheros AR2425) after suspend. This time, we could not find a kernel version where it works after resume. The problem shows up with kernels 3.0.x, 3.2.x, 3.10.x, 3.13.x at least. From the system log: --------------------- kernel: ath5k 0000:03:00.0: Refused to change power state, currently in D3 ... kernel: ath5k: phy0: failed to wakeup the MAC Chip kernel: ath5k: phy0: can't reset hardware (-5) --------------------- lcpci: --------------------- 03:00.0 Ethernet controller [0200]: Qualcomm Atheros AR242x / AR542x Wireless Network Adapter (PCI-Express) [168c:001c] (rev ff) (prog-if ff) --------------------- The adapter works fine in MS Windows installed on the same laptop, so, I guess, it is unlikely to be a hardware issue. Any more ideas how could one debug this? The system log also shows more suspicious messages related to that device: -------------------- kernel: pci 0000:03:00.0: disabling ASPM on pre-1.1 PCIe device. You can enable it with 'pcie_aspm=force' ... ath5k 0000:03:00.0: can't disable ASPM; OS doesn't have ASPM control -------------------- Could they be related? Any help is appreciated.
