Comment 3 for bug 501973

Affected. With a fully-updated kernel, rfkill erroneously reports that the wireless is hard-blocked. The fix in the report - mounting tmpfs over the virtual device in /sys - works.

Ubuntu Lucid 10.04 32bit with an Intel 5300 using the wlagn driver. Key problem: NetworkManager shows the card, but lists it as 'disabled' and un-enableable. The tmpfs trick and a NetworkManager restart fixes the problem.
