The rebuild went smoothly, the same kernel-config was built cleanly. I rebuilt all of the X11-ports and tried starting xdm as usual. The machine rebooted after a panic (see attachment for more details): panic: make_dev_credv: bad si_name (error=17, si_name=dri/card0) Apparently, this is problem has been known to the x11@ folks for a while -- when the new X11-drivers try to load DRM2, the kernels with the "old" DRM in them will panic: http://lists.freebsd.org/pipermail/freebsd-stable/2014-September/079868.html While the recommended work-around -- remove "device drm" and "device radeondrm" from kernel config -- helped me get going, it should not be necessary: 1. There must be no panic 2. If DRM2 can not coexist with DRM, it must check for the condition and report an error. 3. If DRM2 is a replacement for DRM, why not remove the old "device" altogether? No doubt, the x11@ group is aware of the problem. This ticket is intended to help them track it. -- You are receiving this mail because: You are the assignee for the bug.
