Comment 139 for bug 640100

After applying the workaround "intel_idle.max_cstate=0" I have come into some issue when after resuming from suspend (that part seems to be working fine now) the backlighting of my n220 is jumping up and down for some time (with the respective indicator applet visualizations, and no chance to stop it by using keyboard Fn-Up/Fn-Down). This occurs kind of randomly, and goes away after some time - sometimes it can be solved by closing the lid and opening again - i.e. by additional suspend/resume cycle. Is anyone else having this also?
