BUG: scheduling while atomic: swapper/0/0x10010000

This has been occurring ever since I've started using Lucid (since pre-alpha). It occurs whenever I manually turn off wireless connection (flip the switch off) and switch it back on. Even if the wireless is switched off before booting.

The weird thing is, I get the error but I can still use the wireless interface to connect
