Hi,

I have a AR2425 chip in Aspire One laptop. Wireless works fine until I use standby. Every time after resuming from standby after more than few minutes ath5k reports "failed to wakeup the MAC Chip" and after that "can't reset hardware (-5)". Device stays visible in ifconfig, but it can't find any APs or change any settings. I've been trying with 2.6.28,-29,-30,-31. The log shows a try with 2.6.30 with http://www.orbit-lab.org/kernel/compat-wireless-2.6-stable/v2.6.31/compat-wireless-2.6.31-rc4.tar.bz2.
Comment 1 Vesa Vilhonen 2009-08-04 15:01:49 UTC
Can I do something to help with this? Try some patches add tracing or something?
Comment 2 Bob Copeland 2009-08-04 15:25:47 UTC
Sorry for lack of response, I've been a bit busy.  There's a patch on a linux-wireless for you to try:

http://patchwork.kernel.org/patch/38550/
Comment 3 Vesa Vilhonen 2009-08-04 16:46:15 UTC
No problem. I tried the patch but unfortunately got the exactly same error message.
Comment 4 Vesa Vilhonen 2009-08-04 16:46:59 UTC
To be exact, I applied it to that stable 2.6.31-rc4 I mentioned above.
Comment 5 Vesa Vilhonen 2009-08-10 17:19:42 UTC
Is there anything else I could try?
Comment 6 freeseek 2009-09-26 05:28:10 UTC
I have the exact same problem, my wireless card is a
Atheros Communications Inc. AR242x 802.11abg Wireless PCI Express Adapter (rev 01)
and I am using a NC20 laptop. Basically what happens is that some times, completely randomly, the wireless stop working, and dmesg is flooded with messages like this:

I am willing to debug if instructed how. A lot of people using the NC20 laptop have reported the same problem. I am using Ubuntu Jaunty and the kernel is
2.6.28-15-generic #52-Ubuntu SMP Wed Sep 9 10:49:34 UTC 2009 i686 GNU/Linux
Comment 7 freeseek 2009-09-26 05:31:00 UTC
I forgot to say that removing and uploading the module again does not solve the problem. The only solution seems to be to reboot the machine.

Not really, this bug is about failure to wakeup after a suspend, whereas your problem happens at a random time.

Try a recent kernel, I'm pretty sure this has been fixed.
Comment 10 freeseek 2009-09-26 14:04:54 UTC
I should have explained myself better. I used to have the same problem when waking up after suspend. The NC20 laptop had this problem that the screen would not turn back on after going off because of idling and the only solution was to suspend and resume and that's when I had most of wireless problems with the typical messages
ath5k phy0: failed to wakeup the MAC Chip
ath5k phy0: can't reset hardware (-5)
Now the screen problem is fixes but I occasionally experience the same bug every once in a while. I assumed they were the same bug, but maybe I am wrong. I am going to do some testing with the new kernel 2.6.31-11-generic #36-Ubuntu SMP Fri Sep 25 06:37:51 UTC 2009 i686 GNU/Linux and see what happens. Anything I could do to increase the amount of debug messages from ath5k?
Comment 11 blah 2009-09-30 06:05:29 UTC

i also get this error on booting every time for the last year since ath5k came out. i am able to get the card working when using a backtrack 4 livecd however. but my main distro :
Linux zombie 2.6.29-sabayon #1 SMP Wed Aug 19 22:18:09 UTC 2009 x86_64 Intel(R) Core(TM)2 Duo CPU T7700 @ 2.40GHz GenuineIntel GNU/Linux
doesnt like it.
the card is an SRC/5004/52xx one.

i reported this on ath dev mailing list about 4 months ago.
i was advised to try madwifi: i spent several months with that not working.
they advised me to go back to ath5k as madwifi is 'legacy'.

Comment 12 Bob Copeland 2009-09-30 06:09:50 UTC
Okay, well, try a recent kernel, 2.6.29 is quite old in ath5k terms.
Comment 13 blah 2009-09-30 06:36:34 UTC
my distro doesnt have any newer so it would require going out of my distros support which i dont like much. is there any way i can download a module like with compat-wireless or something ? 

also: this point seems moot because ive tested this in backtrack 4 - 2.6.29 - and it works. can you think of any reason why this would be ?
Comment 14 freeseek 2009-10-02 13:10:18 UTC
I have installed the latest kernel from Ubuntu Karmic, that is
2.6.31-11-generic #36-Ubuntu SMP Fri Sep 25 06:37:51 UTC 2009 i686 GNU/Linux
but I still get the same problem. Here is a dmesg output:
ath5k phy0: noise floor calibration timeout (2462MHz)

Again, this happens for no particular reasons other than using the network when it happens, out of the blue. Can I do something to get more debug output? Why is it that even removing and inserting the driver does not make it work again? Couldn't at least a workaround be possible, if nobody is capable to fix this, like a reinitialization when the driver is inserted again? Having the reboot the machine is incredibly annoying and a lot of people are experiencing this same problem from what I read on a forum dedicated to the NC20 laptop.
Comment 15 Bob Copeland 2009-10-02 15:20:48 UTC
Try suspend-resume.  The problem is once the hardware is in a bad state like this, you actually have to disconnect power to it, resetting it doesn't help.

Can you send a pointer to the NC20 forum?  It could be a problem specific to a certain hw revision.
Comment 16 freeseek 2009-10-02 15:58:52 UTC
Wow, that is pretty lame. I guess that means there is no way to disconnect power to the device without suspending or turning off. This is really bad design of the card then. I wish I never bought it now. Anyway, here is the link to the forum:
http://ubuntuforums.org/showthread.php?t=1079314
But it runs for many pages, only here and then it talks about ath5k.
Comment 17 freeseek 2009-10-08 04:04:35 UTC
I tried suspend and resume. It does not help. So it is really the case that the problem is with resetting the card? I am really confused here. Is there anyway I can provide additional debug?
Comment 18 Bob Copeland 2009-10-08 12:38:48 UTC
So just some background -- up until 2.6.30, when we completely rewrote ath5k_reset_hw, there were some issues on some hardware that if you wrote certain registers in the wrong order, the PCI-e interface unit would lock up.  Consequently, any reads from the card just return 0xffffffff, then this usually manifested with the first ath5k_reset and you get 'failed to wake up MAC chip.'  I had this on my hardware in the <= 2.6.29 timeframe.  Usually, but not always, suspend/resume will fix it by powering off the card and powering it back on.

There's an _additional_ bug, which this bug report originally referred to, which is that some cards don't like going to low power state during suspend/resume; this was fixed in 2.6.31.3.  Unfortunately the symptoms are the same.

If you search bugzilla, you may find a patch from me for pre-2.6.30 that did some locking around reset (mostly slowing it down); however it led to hard lockups and I believe the reset rewrite in 2.6.30 obviates it.

Debugging it is difficult (I spent a fair amount of time doing so) but if you wish to give it a try, some printk's of what the driver is doing (register writes, function calls) just before the interface unit lockup would be useful.
Comment 19 freeseek 2009-10-08 16:06:58 UTC
Again, I am using kernel
2.6.31-11-generic #36-Ubuntu SMP Fri Sep 25 06:37:51 UTC 2009 i686 GNU/Linux
I can easily install the next version, linux-image-2.6.31-12-generic (which maybe corresponds to 2.6.31.3? not sure how to check). Do I need to recompile a special version of ath5k or is it just possible to modprobe the driver with some special debugging parameter? If so, how? I have not much experience with that but I am willing to learn. Let me know.
Comment 20 freeseek 2009-10-22 03:33:51 UTC
This is what dmesg says after the device locking up and trying suspending and resuming:
ath5k 0000:01:00.0: enabling device (0000 -> 0002)
ath5k 0000:01:00.0: PCI INT A -> GSI 28 (level, low) -> IRQ 28

ath5k phy0: failed to wakeup the MAC Chip
ath5k 0000:01:00.0: PCI INT A disabled
ath5k: probe of 0000:01:00.0 failed with error -5
Comment 21 Thomas Mudrunka 2010-05-03 23:55:36 UTC
I've got the same problem (older acer aspire) with 2.6.33:
https://bugzilla.kernel.org/show_bug.cgi?id=ath5k-wakeup
(i've created another bug, because at the beggining it seemed to be destroying
EEPROM...)
Comment 22 John W. Linville 2010-08-11 18:03:39 UTC
Does this problem persist with 2.6.35 (or later) kernels?
Comment 23 Thomas Mudrunka 2010-08-11 23:33:33 UTC
John: I am currently testing 2.6.35-ARCH, i'll let you know. is there any particular reason why it should be fixed or you are just curious if it was somehow magicaly fixed somewhere else? :-)
Comment 24 Thomas Mudrunka 2010-08-12 14:48:36 UTC
Crashed again. I have some ideas...

It crashes only when module is loaded, so there can be some workaround mechanism which will virtually "unload" the module to isolate and protect the rest of kernel from problems caused by that card.

Now after wakeup (before crash or module unload) it said me that device is not ready (failed to wakeup) and it was magicaly cured after module reload (for a while until it crashed definetely), so i guess that there IS way to fix card after wakeup, but we will probably need atheros people for this.
Comment 25 John W. Linville 2010-11-23 16:38:35 UTC
Any word from the ath5k folks on this one?
Comment 26 John W. Linville 2011-01-18 18:58:11 UTC
I'm not hearing any similar reports.  Is this issue still relevant for 2.6.37 or later?
Comment 27 John W. Linville 2011-03-17 19:17:26 UTC
Closing due to lack of response...
