Subject: kernel 3.0.0: BUG: using smp_processor_id() in preemptible [00000000]
 code: Xorg/2334

Hi,

Running kernel 3.0.0 (with proprietary fglrx driver), is there a open 
source driver on the ATI side of things that supports this card similar to 
nouveau for nvidia cards if that is the root cause of the problem below?
Or is there a mailing list to discuss this type of problem w/fglrx module 
loaded?

01:05.0 VGA compatible controller: ATI Technologies Inc M880G [Mobility 
Radeon HD 4200]

When this occurs (or sometime after) the wireless network connection stops 
working:
