Subject: RE: PROBLEM: brcm80211 hangs on
 2.6.36-0.34.rc6.git3.fc15.x86_64

Thanks for the input.

The 4313 (Device ID 4327) is pretty solid on the 32 bit staging-next kernel (loads, runs
for days, no issues, etc).

On the other hand, I haven't been using anything other than that kernel recently so its 
very, very likely there are problems with other kernels, especially 64 bit which I haven't even 
attempted yet (but will of course). Please do try out the 32 bit staging-next kernel and let me know how it goes.

Yeah, turning on msglevel produces more (and possibly *much* more) output.  

Let me know what you find,
Thanks
brett
