   It can be many things for sure so it might be helpful for you to 
narrow it a bit; things to consider include:

   CPU - AMD vs Intel
   Graphics - intel, amd, nvidia etc.
   Any 3rd party drivers (nvidia e.g.) - look for 'tainted' in logs.

google can be quite helpful too, as can reading the git logs from kernel 
or bugs on freedesktop.org if you think it might be graphics related.

If you do have any 3rd party drivers, you can try not using them to see 
if makes a difference.

Quite a few reports of problems with both suspend or coming out of 
suspend (I'm equating 'sleep' with suspend as distinct from hibernate here).

Please report back what you learn and good luck.
