sleep
Reply-To: kuba at lbl.pl

hi.
my thinkpad drains 10 times more battery when sleeping than expected.
i have heard that can be a problem with radeon or something similar 
(when sleeping i can still see the display on LCD (without backlit)).
can anybody help me with this issue ? (fix or at least debug so i would
provice more info to developers).


here is my dmesg:
