I recently replaced Ubuntu with Manjaro on my Dell Precision 5520. I’ve since seen it crash a couple times with a signal 6 (abort). I believe I am running X.org 1.20.9-2. The backtrace in /var/log/Xorg.0.log.old looks like this:

Right after that it says to check wiki.x.org, which I have. That led me nowhere obvious. I thought I read somewhere to include the output of inxi -Fa. I tried to attach it but that failed (looks like upload is only intended for images). So here it is inline.

I would appreciate some guidance about how to debug this problem or provide more useful details so others can.
