This has been known for a while (see the kernel bugzilla). The bug report suggests that the reason is a problem with hw crypto.

i can spot a patch in the bugzilla tracker, you might want to try that Bejamin.

The patch is for ath5k and not for ath9k if I understand the discussion and the content of the patch.
I understand that this bug is known for a while, but look like nobody is very interested into it.
I will try the solution of "nohwcrypt=1", but this is just a workaround...
