This one is fixed by commit d50bae33d1358b909ade05ae121d83d3a60ab63f in
mainline. The patch was also sent to stable.

I'm not sure(I've been procrastinating on this one
with reverting commits to see if it helps
the guy that reported this).

From over here though there never was a problem
on my side with the wireless connection(maybe a few disconnects,
but nothing too harsh).

At this point the best thing to do is to see what the
response is from the two gentlemen who where really
hitting this and seem to be running into issues
then go from there.

Im still hitting this so basicly using 2.6.30 until it get sorted. Will try and make
some time to test the different commits. Last time I waited for it to disconnect which
could take 10-40min. Since it depends on the network load Im now going to increase
the load to see if I hit it quicker (and thus finding the error commit).

So in short, its still valid and I will try and make time to fix it :)

Especially if you are using your computer as a router to other computers
and they start screaming every time internet goes down. :(

ah. yeah I'm not doing that over here
just simply connecting to a router and streaming music.
my guess is you can try the commits that I found
but then again might not get you in the right
direction i.g. during the bisect I was watching the
"retry" in dmesg with ath* as soon as I saw that it was git bisect bad
(seems like a new mechanism) as soon as I didn't see
that the commit was good.

In your case you might be seeing something different(not sure though)
because of having the computer as a router etc..

I think its related since ath was rock solid until 2.6.31. I can go 24/7 without
ever getting disconnected from wifihub with 2.6.30. If we both are experiencing
issues post 2.6.30 atleast it should be related to same bunch of patches.
Will see if I can use gfs computer for a couple of hours tommorow
since I need to feed it with traffic. Will start with your commits, will notice
if those turn out same for me.

FYI I see exactly the same symptoms - tons of probe timeouts, usually
very shortly after the association. But I see this with an Intel 5100
AGN so it's either mac80211-related or coincidence. I now went back to
2.6.31 which is perfectly fine for about half an hour. I'll try to
bisect it down a bit, but many .32-rc releases hang on very early in
ACPI code on this box which might make it a pain or impossible.

Still occurs with kernel 2.6.32-rc8.

This time I only rebuilt the glibc src rpm, which also runs its
test suite, but I did not install the new glibc binaries before
the shutdown -r.

I have not been able to reproduce this issue so far. I don't have the exact same HW, but I tested on stock 2.6.31 with 82541 based NIC. More than 3 days now of stress without a problem.

If the reporter can provide some additional information that may be of help:
1. cat /proc/interrupts
2. ethtool -i ethX (where ethX is the interface that is causing the problem
3. lspci -vvv
4. ethtool -e ethX
5. specific settings that may deviate from the default configuration (like MTU)
6. type of traffic that is causing the issue.

Thanks,
