Make sure to STOP all kernel profiling before attempting to
suspend or hibernate your machine. Otherwise I expect it
will hang.
That is not acceptable. People suspend and hibernate machines without
being aware of what applications are doing.
GPROF is a kernel compile-time option. If you don't enable it,
you have nothing to worry about.
Well that's a great hidden reason why noone would ever turn on this
subsystem -- so why is it getting done on it??
