This message contains a list of some regressions introduced between 2.6.30 and
2.6.31, for which there are no fixes in the mainline I know of. If any of them
have been fixed already, please let me know.

If you know of any other unresolved regressions introduced between 2.6.30
and 2.6.31, please let me know either and I'll add them to the list.
Also, please let me know if any of the entries below are invalid.

Each entry from the list will be sent additionally in an automatic reply to

I did a bisect yesterday on this, and the results
seemed to have worked over here by reverting:

75e6c3b72b3ab01c47629f3fbd0fed4e6550bf3a
cfg80211: lower dynamic PS timeout to 100ms

if Kristoffer can try reverting this one
to see, then we can go from there.

No, it is not resolved.

Attachments have been recently added to the bug and it would be highly
desirable for whoever introduced those regressions in 2.6.31 to
examine them and participate in resolving the issue. Alternately,
reverting those ACL caching changes to 2.6.30 status would be equally
acceptable as a solution.

So that just means the driver is broken. Please run

iwconfig wlan0 power off

to fix it then. And the patch below will disable it by default since
it's broken.

OK, so perhaps this patch should be applied until th ath9k driver is fixed? Luis? John?

I applied the patch from johannes and it ended my issues atleast. I ran my machine for approx
2 hours without seeing the disconnect issue (which I usually saw after 15-25min). Cant be 100% of course
but so far so good.

I agree with Justin that we could wait until he gets a chance to test it. It should be accepted
after initial merge (and stable trees) after that I think. Rafael thoughts?

Also, we should notify the atheros people so they could start fixing the driver (in a perfect world).

Best wishes

Johannes, am I correct in thinking that this also solves the decreased signal strength
issue in bug http://bugzilla.kernel.org/show_bug.cgi?id=13807 ?

I can probably test it out, main problem
is where I'm headed internet connection might
not be strong enough to run any kind of media
(hotel connections are only strong enough to retrieve e-mails
streaming music/movies can be a bit much). luckily
I'm away only for a few days.

With 2.6.32-rc8, it works for me.

I tried the patch last night as I said, thought that it was working. But not long after
sending that email I started seeing those disassociations again (that not appear at all in 2.6.30).
So doesnt seem like it was due to that after all. :(

Status of this bug in mainline didn't change. However, there are
patches to fix this issue:

1. http://marc.info/?l=e1000-devel&m=125659409119946&w=2

Works -- interface is brought up properly. However, kernel warns
about two allocation failures (and succeeds in thrid attempt).

Patches to make warnings appear every 10th failure have been
presented. What this basically means for me is that failure message
would pop up every 5th suspend-resume cycle.

(Patch has a typo that needs fixing: s/struct cbs/struct cb/)


2. http://marc.info/?l=e1000-devel&m=125637894721936&w=2

Works without any warnings. Sadly, patch is far more intrusive.

Thanks.

Its quite possible I guess. I will do an bisect and see if I can
get anymore output.

Hi!

Sorry for not answering before, I've been running 2.6.31 patched for all
this time and the results are a bit dissapointing...

The first run was for almost a month and ended up with half a hang, I could
read on the console that there had been an error on one of the disks, dma
error, the keyboard was working, getty seemed to work but then login didn't
show up when entering the username even though the disks led was flashing
when I operated the console entering usernames and all that. This hang was
not like the hangs I had before, don't know if it was due to the patch and
the unknown operation arriving to the IDE disk, but the message that the
patch was supposed to display was not displayed at all.

The second run is current run I believe, currently it has an uptime of 18
days and not problem was showed over this time.

So... I'm afraid I'm not able to reproduce this and maybe the whole problem
is hardware related, even though the machine had been running with 2.6.30 in
a stable way, it is an old machine, so maybe it is not as healthy as I
believed, and even though memtest doesn't show any errors there could be
some dma problems or other weird things happening around :-(

So... I'd say you can close the bug and if I happen to find it again... I'll
report it again.

Sorry for all the noise.

Regards...
