Hi! Are you still having this problem? What version of FreeBSD are you using? Are you using the graphics/drm-stable-kmod or graphics/drm-next-kmod ports?
I am rolling with latest RELEASE, so 11.1-RELEASE-p10 now. I am not using drm-*-kmod ports. I have loaded i915kms.ko, which is in the base, right? The last crash was about 3 weeks ago, but unfortunately I no longer have latest kernel crash log. I can still wait and watch it and post crash logs or you can close it.
It's been a few weeks. Have you seen the crash again?
Yes, the computer crashed about 3 times but /var/crash is empty on 11.1-RELEASE-p10. I have dumpdev="/dev/ada0p4" in rc.conf (it worked previously), but the crashlog stopped storing in /var/crash - I need to investigate it another time, so I am closing this issue and I will wait for FreeBSD 12... Thanks!
Check that you have room in /var/crash, so that it isn't filling up and failing to dump. You could also jump to FreeBSD 11.2 (it's currently in RC2, slated to be released later this month) and try with graphics/drm-stable-kmod instead.
