Subject: [tainted,fglrx] page allocation failure: basic meaning of log
 messages?

-----BEGIN PGP SIGNED MESSAGE-----
Hash: RIPEMD160


Dear developers, 

I've found the following messages in my syslog after a suspend2ram cycle, 
(And similar repeated a few times, all between "freezing userspace" and 
"back to C".) 

I know the system is tainted / running the fglrx module, and (to me) it 
even looks like this might be causing the problem.

So - I'm not asking for a solution, but could cou please please give me a 
rough hint what the error message means???

TIA, best, Andreas 

(Of course I'd be happy to provide more info.)
