The system now crashes on loading /boot/modules/i915kms.ko I build and install graphics/drm-kmod and graphics/drm-fbsd12.0-kmod together with the kernel. If i915kms.ko is loaded via kld_list in /etc/rc.conf at boot, the screen goes blank upon loading the module and does not react any more, powercycle is required. If I load the the module manually after a successful boot, the screen goes blank and the system reboots after a while; on reboot a dump is found and written to /var/crash. Kernel config is GENERIC with added options WITNESS and WITNESS_SKIPSPIN CPU is a Celeron 2955U (Haswell class) and the graphics controller identifies as 'Haswell-ULT Integrated Graphics Controller' in pciconf. Any suggestions how to proceed from here? Any usefull information that I could extract from the crashdump? Wolfgang
