Now (with r339186) it seems that drm-next-kmod is the only usable option. However, I'm sorry to say: - it does feel regressive, compared to working without drm-next-kmod with earlier versions of -CURRENT. I can no longer find a way to reliably suspend (sleep) the notebook. At the time of writing my part-working configuration is as outlined below. However – frustratingly – for a while, an hour or so ago, it seemed as if the same configuration was useless; after a point, the screen would go blank (grey) and things would progress no further e.g. no login manager (sddm); no response to Control-Alt-F2; no response to Control-Alt-Delete. The apparent unpredictability leading to a dead-end situation has created a sense of unease; now I'm genuinely afraid to test suspend :-( For reference – working at the moment with UEFI, without CSM ============================================== $ date ; uname -v Sat  6 Oct 2018 01:51:53 BST FreeBSD 12.0-ALPHA8 r339186 GENERIC-NODEBUG $ grep hw.acpi.reset /boot/loader.conf # hw.acpi.reset_video=1 $ grep debug.acpi /boot/loader.conf debug.acpi.resume_beep=1 $ grep adeon /etc/rc.conf kld_list="/boot/modules/radeonkms.ko" $ pciconf -lv | grep -C 2 adeon vgapci0@pci0:1:0:0:     class=0x030000 card=0x17a9103c chip=0x68411002 rev=0x00 hdr=0x00     vendor     = 'Advanced Micro Devices, Inc.
