Rajkumar, yeah i also thought using pcie_aspm=off would disable ASPM completely, so i dont know what is going on. My laptop is a sony vaio SVE model, and it has a crappy BIOS designed specialy for windows 8 and all that UEFI crap. Las time i checked the BIOS it was really a simple one, not many options to deal with, but i will check again if the issue reappears and try the patch. Until now everything is fine with ASPM disabled on both the root complex and wifi card.(ath9k is loaded with ps_enable=1) Btw as i said in a previous email, if ASPM is disabled completely, leaving powersave mode on for the ath9k module meaningless? in other words would powersave work with ASPM disabled but ath9k module loaded with ps_enable=1 ?
