Good to know, that's what I assumed was happening to him.
Device goes into suspend, SetCpuSpeed catches it and throttles CPU, and then at some point before the device resumes and SetCpuSpeed bumps the clock speed back up the process crashes. If that happens, running SetCpuSpeed.exe from \Storage Card\Program Files\SetCpuSpeed is fine.
I really hope Netripper releases v3 soon or Oruam comes back with a new build of SetCpuSpeed...I really don't want to debug it myself.
