Hi,
As a good hacker I was using frysk while traveling with my laptop to
debug some program. Imagine my surprise that when I had to switch trains
my laptop didn't want to suspend. The cause was frysk (!). Only when I
quit my frysk debugging session could I suspend and change trains.
Meanwhile I noticed the same thing with gdb. When you are attached to a
process the kernel refuses to suspend. This is primarily a note to
myself to not forget about this incident, investigate a bit more when I
am back, and file a proper bug report against the kernel/utrace.
Cheers,
Mark

I filed this against the upstream fedora kernel here:
