Hi, Vincent,
There are lots of WLAN log in logcat. I am wondering if you know what happened or any suggestion?

These netlink messages seem from wifi driver, I am not sure the detail here.

Paul,
even though I am not sure, but might be related with bug 1142384. We need logcat from that bug to confirm

Henry, perhaps you can check on the logcat and let us know?

Hi Walter,

Did you mean the logs like

"03-16 11:59:32.383   214   214 V WLAN_PSA: NL MSG, len[048], NL type[0x11] WNI type[0x5050] len[028]"

I don't know where these logs come from but I do see these kind of logs 
all the time. So, I don't think there's anything wrong with the logs.

Is it possible that you look into it more? We also don't know any further information on this one. We can get you a phone with adb shell available, do you like to take a look?

If you mean looking into the WLAN log more, I would say I have no idea and 
it totally has nothing to do with this issue. But I am willing to take
a look to find some directions for you :)

[Ken Chang[:kenkai]]

Henry, any feedback?

Comment 17

[Henry Chang [:hchang]]

It isn't related to wifi module at all so I am not looking into this issue for now. Thanks.

Comment 18

[Henry Chang [:hchang]]

Or I should say: if I were in charge of this bug, I wouldn't start from wifi and there's no useful information in the log to locate the potential root cause.
