hwinfo output

I upgraded my system to 15.5 recently hoping that this would give a nice consistent/stable base for eg. stap usage :-) Quite possibly this is some weirdo upgrade artifact from tumbleweed -> 15.5 but anyhow - I just want to check that system-tap works nicely out of the box for someone :-)

my stap script:

#! /usr/bin/env stap
probe vm.write_shared {
  print_ubacktrace()
}
probe begin {
  printf("Starting data collection\n")
}
probe end {
  printf("Terminating data collection\n")

the compile output:

sudo stap online-memory-cow.stap

I hope that helps someone.
