(I'm guessing a remote GNU/Linux target).

Try:
	(gdb) help handle
	(gdb) handle SIGPWR pass nostop noprint
I suspect the SIGPWR is being used as part of the thread implementation. 
  You're probably also going to find that threads don't work very well 
remotely, I don't know of many debug agent implementations that support 
threads.
