Ath9k crash after suspend/hibernation.

Hi!
I'm not a native english speaker, so please don't be harsh on me
I think it started after upgrading the kernel to 2.6.39, but it still happens at the 3.0.7-1. It worked fine some time ago for sure... I cant use lts kernel, because I cant get X to work good on it.... After waking up from suspend or hibernation, "iwlist scan" outputs "No results". When I try to reload ath9k using modprobe, I can see this in dmesg:

IRQ #17 is:

Of course I've tried booting with irqpoll, but it doesn't change anything (and it still suggests me, to try this).

Re: Ath9k crash after suspend/hibernation.

Put this in /etc/pm/config.d/modules

SUSPEND_MODULES="ath9k"

Re: Ath9k crash after suspend/hibernation.

I've already tried that, it doesn't work. Doing it by myself doesn't work neither:

[root@Dmitrij kaz]# iwlist wlan0 scan | head -n5
wlan0     Scan completed :
          Cell 01 - Address: 74:EA:3A:E3:B1:C8
                    Channel:1
                    Frequency:2.412 GHz (Channel 1)
                    Quality=41/70  Signal level=-69 dBm
[root@Dmitrij kaz]# rmmod ath9k
[root@Dmitrij kaz]# pm-suspend
[root@Dmitrij kaz]# modprobe ath9k
[root@Dmitrij kaz]# iwlist wlan0 scan | head -n5
wlan0     No scan results

Re: Ath9k crash after suspend/hibernation.

I run Ubuntu now, but putting

SUSPEND_MODULES="ath9k ath9k_hw ath9k_common"

into /etc/pm/config.d/modules worked for me. I got that from arch's pm-utils wiki page.

Re: Ath9k crash after suspend/hibernation.

I don't have this issue for a few months now, one of updates fixed it . My SYSPEND_MODULES has only ath9k (and xhci, but that's another thing).
