And I also confirm the bug, exact eroro messages as oguzy
On 11.10 with kernel 3.0.0-14-generic-pae
System: Acer aspire 5750g and atheros AR9287 wireless network adapter

It seems that the 3.0 kernel reintroduced the bug.
The wireless works ok for awhile, sometimes minutes, sometimes an hour and then stops suddenly.

It takes a powerdown/reboot to work again.

Can somebody check if the patch was applied in the 3.0 kernel? It does not seem to ban encryption problem, but more a race condition where the driver messes up the card.
