Dear wireless experts, I have been trying to get basic WoWLAN to work with the following configuration: - Intel Corporation Wireless 7260 (rev 73) with in-tree iwlwifi driver - Kernel 4.10.0 (on Gentoo Linux) - Very recent firmware version for the card and revision: iwlwifi 0000:0a:00.0: loaded firmware version 17.459231.0 op_mode iwlmvm iwlwifi 0000:0a:00.0: Detected Intel(R) Dual Band Wireless AC 7260, REV=0x144
I try to do: $ iw phy phy0 wowlan enable magic-packet $ iw phy phy0 wowlan show WoWLAN is enabled: * wake up on magic packet However, when trying to suspend to RAM ( echo mem > /sys/power/state ), I get: [46656.403767] dpm_run_callback(): wiphy_suspend+0x0/0x97 [cfg80211] returns -16 [46656.403769] PM: Device phy0 failed to suspend async: error -16 [46656.967002] PM: Some devices failed to suspend, or early wake event detected It also happens with more complex configurations (e.g. TCP connection WoWLAN mode). Only after: $ iw phy phy0 wowlan disable I can suspend normally again. I found an earlier report here: https://bugzilla.kernel.org/show_bug.cgi?id=109591#c25 from somebody using kernel 4.6. Is this a known issue? Is WoWLAN supposed to work with this hardware (I guess it's quite wide-spread)? If possible, please ping me directly in replies, I am not subscribed to the list (but will try to check gmane regularly). Cheers and thanks for any support, Oliver
