It seems completely weird that an existing file with a line commented out have any impact. Can you please send the output of: cat /sys/module/iwlmvm/parameters/power_scheme in both cases. Also - what code base are you using? Since this is surely not related to PCI, please remove them in your reply. (I keep them here to have them see my mail :)) ��.n��������+%������w��{.n�����{���zW����ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
