Comment:

 It sounds like GHC itself has hit an infinite loop, which will result in a
 deadlock and the behaviour you're seeing.  It could be a bug that only
 happens on powerpc.  Is the GHC build on Debian Linux/PPC registerised or
 unregisterised?  That is, is it using the native backend or compiling via
 C?

 Adding `-v` to the command that hangs might help.
