Seems like the wpa_s is indeed toggling the device. I don't have time to play with that right now. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

I guess the question is how we get into this situation to start with? About the only thing I can imagine is that we fail somehow during initialization (without printing any other message) and higher layers like wpa_supplicant/network-manager/... simply try to bring up the device over and over again? johannes -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

On Fri, Dec 11, 2015 at 10:59 AM, Luis R. Rodriguezwrote: > I could bisect *if this issue > is not known*, but it may take a while... So this is interesting.. The opensuse 4.2.4 kernel worked, but I tried my own vanilla 4.2.4 kernel and that didn't work. This lead me to believe this might be a config issue. I tried the same config on v4.3, v4.2 and v4.2.4 and all fail with the same issue! I just tried a base config from opensuse, then localmodconfig, then 'make xenconfig' (which I need) and that worked.

iwlwifi - L1 Enabled - LTR Enabled loop
Using 4.4-rc4 and today's wireless-testing (master-2015-12-10), and the latest firmware on linux-firmware, my wireless driver runs into a non-functional loop rambling about "L1 Enabled - LTR Enabled loop". Reverting back to an older kernel works. I could bisect *if this issue is not known*, but it may take a while... If you are already suspicious of a commit lemme know, and I can try to revert. Otherwise if there's a firmware version that is supposed to work I'm happy to try that. Device: Intel dual band wireless AC 7260, REV=0x144 Firmware version: 16.242414.0 (linux-firmware upstream) I also tried: Firmware version: 17.246894.0 op_mode iwlmvm (latest on iwlwifi/linux-firmware.git) I run into the same issue with this version as well though.
