There was an issue causing kernel panic for amdgpu and radeon on suspend/resume that has been fixed. It should be available in an updated pkg later this week. > Try drm-stable or drm-devel. drm-devel will require a rather recent 12/13-CURRENT. Now: $ date ; uname -v Sun 23 Sep 2018 07:16:54 BST FreeBSD 12.0-ALPHA7 r338892 GENERIC-NODEBUG $ uname -a FreeBSD momh167-gjp4-hpelitebook8570p-freebsd 12.0-ALPHA7 FreeBSD 12.0-ALPHA7 r338892 GENERIC-NODEBUG amd64 $ pkg info drm-next-kmod | grep Version Version : 4.11.g20180822 $ grep -i radeon /etc/rc.conf | grep kld # kld_list="/boot/modules/radeonkms.ko" # kld_list="radeonkms" It seems that working without any drm-next-* and booting without CSM is the best combination. There's the tearing during most of startup, but it's not a showstopper. For single user mode, I have a mental note to F10 at boot and temporarily enable CSM. Temporarily, because with CSM I can't resume from suspend. ---- If I un-comment this: kld_list="/boot/modules/radeonkms.ko" – then the display goes blank, but remains lit, before startup completes. No response to Control-Alt-F2, no response to a normal press on the power button, it's necessary to force off the computer. If I'm not mistaken, drm-next-kmod was _less_ troublesome with a slightly less recent -CURRENT. I could use the computer, but there was a tendency to (for example) flicker badly, most noticeable with a VGA display (connected via the HP dock for the 8570p) after some idle time. I often found the flickering at the lock screen of KDE Plasma 5.Received on Sun Sep 23 2018 - 05:01:28 UTC
