Just curious if others have had similar results with ath10k randomly crashing when 802.11w (option ieee80211w) is enabled.

From my openwrt trunk builds for the Ubiquiti Unifi AC-Pro, I have observed the following for QCA988X driver firmware-5.bin_10.2.4-1.0 when 11w is enabled in hostapd config:

build 00016 - not tested
build 00029 - broken
build 00033 - WORKS, 4+ weeks uptime no crash
build 00037 - broken

I am using hostapd-full.  And by broken I mean the behavior in flyspray #333 is evident.  When 11w is enabled the radio will randomly crash between 5 min and 5 hours uptime with the same error as documented in fs#333.

Yes you're not alone. FS#333 is there for a reason.

build 00016 - not tested
build 00029 - broken

build 00016 - broken

build 00033 - WORKS, 4+ weeks uptime no crash

I'll give this one a try. I'm still on 00016 but with 802.11w disabled.

Please add your findings to FS#333, to have all informations at a single place. It looks like the relation of 802.11w and the crash was never mentioned in the ticket.

Thanks for the reply.  Don't waste your time with build 00033.  A day after I posted it crashed, apparently just to prove me wrong.
