Comment 1 Pavel Panchekha 2015-03-29 19:24:56 UTC
The initialization for iwlwifi seems to be: Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0: loaded firmware version 18.104.22.168 op_mode iwldvm Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEBUG disabled Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEBUGFS disabled Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0: CONFIG_IWLWIFI_DEVICE_TRACING enabled Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0: Detected Intel(R) Centrino(R) Advanced-N 6205 AGN, REV=0xB0 Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0: L1 Enabled - LTR Disabled Mar 28 12:40:17 thinkpad kernel: EXT4-fs (dm-2): mounted filesystem with ordered data mode. Opts: data=ordered Mar 28 12:40:17 thinkpad kernel: ieee80211 phy0: Selected rate control algorithm 'iwl-agn-rs' Mar 28 12:40:17 thinkpad kernel: iwlwifi 0000:03:00.0 wlp3s0: renamed from wlan0 which suggests that it is loading firmware iwlwifi-6000g2a-6.ucode, despite the modinfo reporting otherwise (I think that is a known bug, I have both files on my system).

I'm also experiencing what I think is the same bug. It's been happening since at least 3.17, although seems to happen less often now that I'm on 4.0.0rc4 and firmware version 12.16.25. Hardware is Lenovo Yoga 2, wifi card is intel 7260. The bug for me most often happens after resuming from suspend. Dmesg output attached.

This really looks like a duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=91171. Please see a workaround there. @Julian: in your case, the PCI bus decides to remove the WiFi NIC from the bus. Unfortunately, I can't know why. Debugging this kind of issues is almost impossible without reproducing with a PCI analyzer which is not the type of equipment everybody has at home... Please make sure you have the latest BIOS etc... Beyond that, I can't do much. @Pavel, your bug looks really similar. You can try the workaround mentioned in the bug above. Note that the exact command may change based on the position of the device on the PCI bus.

In case this helps anyone this was linked for me to power state management, if you BIOS has access try disabling Active State Power Management (ASPM) on the PCIe lane connected to the WiFi chip.
