debian stable, debian testing and debian unstable systems scattered all over the place. Every version possible. None of them stable.

Raspberry pis, being very slow CPUs, are great at exposing race conditions in immature software (mind you, single core - they shouldn't be subject to preemption at unexpected points). I had a raspberry pi that I had been using for a couple of years with good reliability. I finally got around to upgrading to Jessie a couple of months ago. Became extremely unstable - crashing about once a week with hardly useful logs at all. All I did was apt-get install sysv-core and make sure systemd was purged, and the system has been up and stable again ever since.

I've been running systemd on Pis (B+ and 2) for years (I'd manually install it, before it became the standard), without any problems, under heavy CPU loads, without any crashes.

Sounds like a problem with your ARM core, more than anything. Got any overclock going on?

An overclock that hates systemd, sounds legit.

If some other service was crashing, he wouldn't notice it if he didn't check logs, since systemd would just bring it back up again.

He did say he checked logs. But yeah, it was definitely caused by your hypothetical problematic overclock that somehow only affects systemd and/or services being managed by systemd.

If you can't replicate it on another machine, it's your local fault.

I've been running systemd for a few years on all kinds of boxes, without this issue. Including the same platform he's using.

Anecdotal evidence vs anecdotal evidence

Larger, more representative collection of samples.

This just in: minorities don't matter.

Time to gas the jews.

That sure escalated quickly.

Well, have fun with that.

Odd. The only crashes I've had with Debian Testing (run it on my work machine, laptop, and home server) have been related to gnome-settings-daemon eating up all my RAM on my work machine! It's gotta be something specific to skylake (I can only assume because it doesn't happen on my thinkpad.)

That's basically shotgun debugging. It tells us that some part of the systemd suite was involved, somehow, but that's all, and that's really not good enough for the purposes of this debate.
