I've been testing the mac80211 bump (4.18 RC7) in the field for some
It's currently running on roughly 40 moving devices (~90 wlan
interfaces) at various distances.
(The devices are mounted on windmill's and vessels.)
All of them are running in IBSS mode, 802.11n, 5.8G, HT40, Long GI.
Enabling dynack triggers crashes in this mac80211 version. (RCU stalls)
I haven't seen these in the past few months running the current OpenWrt
4.14-RC2 mac version.
I don't know if this will also occur in AP or MESH mode .. hence I'm
reporting it here ..
Apologies for dragging you into this thread but, being the lead
regarding mac80211, maybe you have a clue where this gets triggered.
Being the designer of dynack, maybe you have an idea?
