Reproduceable kernel panic on DS4 disconnect; Magic REISUB didn't work

For whatever reason, I have bad luck with cables so after a few months I start to get random disconnect/reconnects for my game pads, at which point I replace the cable and everythings good again.

This time was a bit different. This time after a few seconds everything locked up to the point where magic REISUB (which I have used before so I know it works) didn't work. It happened last night too, but I thought it was related to something.

Below is the output of `journalctl -b -1| tail --lines=600` (so there is a lot of it). It captures both the controller event, as well as everything the kernel was trying todo before I hit the reset button.

Re: Reproduceable kernel panic on DS4 disconnect; Magic REISUB didn't work

As first steps I would update to the latest and greatest kernel™ and not load the vbox modules.

Even if the machines crashes I would try to get the kernel not to complain that it is tainted (ex.: Aug 18 09:26:06 host kernel: CPU: 3 PID: 20304 Comm: watch Tainted: P      D    O      4.17.14-arch1-1-ARCH #1).

After you manage that we can go from there and if the conclusion is that it is a kernel bug it will be much easier to report it upstream if you are not using any module that taints the kernel.

I upgraded the kernel and uninstalled VirtualBox (I can't remember the last time i used it).

Does this cover what you are suggesting?

Re: Reproduceable kernel panic on DS4 disconnect; Magic REISUB didn't work

As a starting point yes. If the machine still crashes then it's a matter of trying to find a way to reliably crash it and trying to figure out why it is crashing, or at least narrow it down as much as possible before reporting the problem upstream.

On the same note it would help if you know from which kernel version you started to have problems. The more you can narrow down the problem before you report it upstream (if it is a kernel bug) the better chance you have that someone will take time to look into the problem. Look at it like this, who would you help, someone who complains "my machine crashes, please help and fit it" or "my machine is crashing if I do A, B and C. I have narrowed down the problem to change D, what else can I do to help fix the problem?"
