Can you still not use wireless even when rfkill reports > "RFKILL event: idx 6 type 1 op X soft 0 hard 0" ? No. I can use wifi if rfkill reports "RFKILL event: idx 6 type 1 op X soft 0 hard 0". My problem is, that since 2.6.31-rcX Fn+F5 toggles soft rfkill state. It did not happen in 2.6.30 and earlier. In that case, Fn+F5 triggered an acpi event (key press). Now, it triggers acpi eveny *and* touches soft rfkill of WIFI. I like the previous behavior, i.e., don't touch anything, just report acpi event. -- Lukáš Hejtmánek
