Another box, running as a server with CURRENT on-top of a Intel(R) Core(TM) i3-3220 CPU with Ivy-Bridge HD2500 graphics, crashes/blanks screen when going into graphics mode with vt() (having kernel modules drm2 and i915kms already loaded via loader.conf). This hardware is now for two years in use and the CPU is much older. The CPU is about to be replaced by a XEON E3-1245 v2 with P4000 iGPU graphics (only). At this moment, I'm highly afraid of having hardware that is not working even with CURRENT.
