Thank you for that. It seems like my system reacts the same way - I've
re-enabled DPM and set the perf level to something that isn't auto. It's not
crashed on me for about an hour now which is better than it did before.

I've also tried your tool - the service doesn't actually set the dpm parameters
to 'low' and 'battery' for me. Maybe some issue with permissions involved. But
dpm-query works fine and it great for convenience. Thanks for that as well.
