I have some advice:
 1: Be sure before suspend have not unused device to used.
   I'm make all the possible device into module, before suspend rmmod
it as possible, after it reload it.
 2: You can enable swsusp2, that's useful debug.
   before suspend do  
     echo 6 > /proc/swsusp/default_console_level
 3: shared you kernel information.
    dmesg >> /tmp/bug.log
    cat /proc/swsusp/debug_info >> /tmp/bug.log
    send /tmp/bug.log to LKML.
