Just had another freeze at suspend. Display was still on, but frozen right in the middle of the fade between desktop and lockscreen appearing before machine should have suspended (same thing as first occurence). So this bug is really about a failure to suspend, since it actually never manages to reach that state.
I find nothing interesting in any logs under /var/log. The last thing that appears in pm-suspend.log before freeze: Fri Apr 4 23:42:00 CEST 2014: performing suspend ** Summary changed: - [Dell Inc.
