Everytime my laptop goes to sleep (low battery), wireless adapter crashes. This makes the system completly unusable. I cannot remove the driver, kill it, or restart NetworkManager. I cannot reboot neither.

I need to find a way to fix it either with a new driver, or patching the existing one. Any suggestions?
