Suspend and hibernate worked on 10.04. Following upgrade (clean install) failed to resume from suspend and hibernate. pm-log indicated success, computer powers up, but display is blank.
Could successfully suspend/hibernate and resume from recovery console using pm-suspend/hibernate.
Adding radeon.modeset=0 meant that suspend and resume now work.... But this messed up my dual monitor configuration and had to create xorg.conf file.
Not sure if mine is exactly the same issue:
Maverick 64 bit, ATI graphics card
