I have this problem with Karmic and the problem is reproducible. First suspend and resume works, second suspend results in services stopping but the computer not entering sleep. The only option is to kill the power.
By Nemtudom's suggestion, I tried executing "sync" before suspend and found that sync works before the first suspend, but hangs before the second suspend. In addition, my kernel log shows numerous messages saying: INFO: task sync:##### blocked for more than 120 seconds This message appears regardless of whether I manually run sync or not. Please help!
