Here's the log you asked for:
http://diff.cc/tmp/kernel_iwlagn_2.log.bz2

As I said, this problem does not occur with the Windows driver. You
said you are actively working on it. Does that mean, the problem is
known to you?

Cheers,
Henrik

we are seeing performance issue and still can not root cause the
problem. that is the reason I send you 2 patches for testing. We are
very active working on fix the performance problem. the symptoms might
be different, but we aware there were issues.

Thx

Yes. I just did, once again, to verify it. No change, unfortunately :(

It was the same. I was hoping a newer kernel might contain a fix of
some sort, that's why I updated it.

Here are the logs: http://diff.cc/tmp/kernel_iwlagn_3.log.bz2
They were made with "11n_disable=1" and without the patches posted by Wey-Yi.

I see. I hope the log is useful to you. I'm not sure, but this issue
seems to be slightly different to your average performance issue. My
Android device needs 1 second to completely load the Router webpanel,
whereas my laptop with the Intel chip needs 30 seconds.

I'm afraid the patches did not make any difference. Oh btw, I did
apply them before making the log. I believe that was your intention.

One experiment if you can help us to test.

please reset the repository to
commit#1f7b6172db86e9ab2b4cd794441bb2c40ab287fc

and give a try to see if you still seeing the issue.

Thanks
