Comment 39 for bug 1016181

Hi there,
I have an AR9285 adapter and got crazy with it. As described by others I also had the following errors irregularly and my wireless-adaper then didn't wake up AFTER resume from suspend and just a reboot could revive it. I'm running Ubuntu 10.04 Lucid and tried several kernels and backported wireless drivers. I also tried ndiswrapper with several windows-drivers but the same problem occurred again.

[ 7144.465844] ath: Chip reset failed
[ 7144.465861] ath: Unable to reset channel (2422 MHz), reset status -22
or
[107330.931497] ath9k 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
[107330.931522] ath9k 0000:02:00.0: setting latency timer to 64
[107331.046361] ath9k 0000:02:00.0: Failed to initialize device

[107331.046468] ath9k: probe of 0000:02:00.0 failed with error -5

The network-manager then says the device is deactivated. However I found a simple WORKAROUND which more or less fixed this issue. Try:

sudo iwconfig wlan0 power off

Also I disabled in gconf-editor:
/apps/gnome-power-manager/general/network_sleep

Probably the first command did the trick. It seems to turn off the power management of the adapter what should result in higher power consumption. Nevertheless better then rebooting all the time.
Currently I'm running 3.0.0-31-generic on an Asus 1005PE. I hope it won't occur again. Btw, I red somewhere that this has something to do with static electricity and the USB ports (?). But I can't find the link anymore.

Any other progress on how to really fix this?

Good luck!
