I have the same defect in my laptop ACER Apire 5610Z with Atheros AR2413 802.11bg.

I try to use the script to eliminate the Jombo problem but without succes:

Bureau$ sudo bash enable-aspm 
Root complex:
Long loop while looking for ASPM word for 00:1e.0

Endpoint:
Long loop while looking for ASPM word for 06:02.0
