[ath9k-devel] Weird Atheros 9485 http connecting problems

[Arkh4mKn1ght <arkh4mkn1ght@gmail.com>]

Ok bad news, the issue happened again both with ASPM disabled on the 
root complex and atheros card and with powersave on and off. I will test 
the patch that rajkumar sent me and i will be back to you guys.

Greetings
