I have a test pc with 3x AR9590 and 2x AR9390. Machine is based on i7
and hyperthreading is on so I have 8 cores.
I am using latest wireless testing ath9k and 3.8rc7 kernel.
What I see is that for some extended periods odf time beacons are not
processed in ieee80211_rx_mgmt_beacon
and that's why I get beacon loss. I am using 30ms beacon period.
What is really funny, that I get this beacon loss message every
second. Like is sth was locking ifmgd->mtx mutex
at constant intervals.
I will try to disable all cores and run in again to see if it's rcu
problem.
You could also try wireless-next or wireless-testing to pinpoint if the
problem is in wireless code or not.
I see it on wireless-testing and mac80211-next. I will try with other
driver later today.
I can see also other problem like authentication frame always timing
out the first time
but I will handle it later.
It has turned out that I had bad irq, switch to polling problem. Without
interrupts for wireless
cards I will for sure see such problems.
Sorry for spamming.
