Description Tomasz "CeDeROM" CEDRO 2019-11-07 19:43:01 UTC
Hello world :-)

I have just upgraded my machine from 12.0-RELEASE to 12.1-RELEASE with `freebsd-update upgrade -r 12.1-RELEASE`. Unfortunately the DRM module causes machine to reboot on load. I had to get into single mode and remove DRM and i915 modules from rc.conf. I cannot see a DRM for 12.1 yet. Rebuilding module does not help. I am without DRM right now unable to use external monitor/projector.

Any hints welcome :-)

Description    :
amdgpu, i915, and radeon DRM modules for the linuxkpi-based KMS components on
amd64, i915 and radeonkms DRM modules from the former base DRM component on
other architectures.
Metaport for different versions of Linux DRM based on the FreeBSD version
in use. This port encompasses the recommendations of the FreeBSDDesktop team
of DRM versions for FreeBSD versions based on the last update to the LinuxKPI
in that code base. In general, the most recent supported stable DRM for a give
FreeBSD version will be installed. CURRENT receives the most recent development
This port does not however hinder the expert user to make other decisions and
continue to install DRM ports directly.

Could that be related?
