[ath9k-devel] ath9k dies on resume

[nornagon at nornagon.net]

Hi all,

I have an AR5418 (in a Macbook Pro Santa Rosa). I'm running Debian unstable, with a custom-compiled kernel version 2.6.28.1. When I resume from suspend to ram, the interface fails to associate with the AP, and the following line is printed in dmesg:

Jan 29 21:06:41 motoko kernel: [31601.244160] ath0: No ProbeResp from current AP 00:1e:e5:7f:0d:1f - assume out of range

If the wifi signal is weak, sometimes ath9k will deassociate and then produce the same message, then refuse to reassociate.

Removing the module and reprobing it fixes the problem, but is not a solution.

On old kernels removing the module would be the right approach, mac80211 only
got suspend/resume support unti recently in the wireless-testing git tree.

Please see this on how to get the latest ath9k:

pm-suspend is working here.
