Ahh, yes, the baloo pain ... You could configure baloo to only index parts of your filesystem you care to find when running semantic searches. I typically switch it off completely, or only allow it to index a small part of the /home filesystem. If you have it enabled and it indexes not only file names but also content, plus emails and what have you, then it will chew up an inordinate amount of resources. > When closing the lid it try for 20 seconds and gives up.

It seems your baloo process eats up all your RAM and when the time comes to put the OS to sleep, there is not enough RAM to do so. I don't know if using a swap file or swap partition would help, but controlling how much baloo is indexing will help both in terms of load on the CPU as well as in terms of RAM when awake and RAM when you suspend it.
