Hi,

I was to fast when saying in September that I do not have any issue with
this NIC: under havy SCP traffic (let's say some GByte) the connection
locks and I have to run 'netif restart' to wake it up;

it seems that powersave is off:

# ifconfig wlan0 list sta
ADDR               AID CHAN RATE RSSI IDLE  TXSEQ  RXSEQ CAPS FLAG   
00:13:f7:0d:08:48    2    7  54M 35.5    0   1219  64016 EPS  AE RSN

the kernel is 11-CURRENT (r269739) and I have IEEE80211_DEBUG enabled:

# fgrep IEEE80211_DEBUG sys/i386/conf/GENERIC
options         IEEE80211_DEBUG         # enable debug msgs

# wlandebug -i wlan0 +state +power
net.wlan.0.debug: 0x0 => 0xc0000<state,power>

In /var/log/messages I see now lines like this:

# fgrep kernel /var/log/messages
Oct 26 08:22:44 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode 
on
Oct 26 08:22:46 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode 
off
Oct 26 08:27:46 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode 
on
Oct 26 08:27:48 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode 
off
Oct 26 08:32:48 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode 
on
Oct 26 08:32:50 unixarea kernel: wlan0: [00:13:f7:0d:08:48] sta power save mode 
off

every 5 minutes...

Who is switching this on/off?

thx

        matthias
