Description lumiwa 2019-01-05 23:01:38 UTC
Created attachment 200816 [details] xorg.log and part of /var/log/messages My system is FreeBSD 12.0-RELEASE (amd640), new installed on the new hard drive. Computer is iMac with Radeom 4850 graphics card, the boot is UEFI and everything works except graphics card problem. When I kldload /boot/modules/radeonkms.ko I got black screen and computer is still responsive. I try also to boot computer with hw.syscons.disable=1 in /boot/loader.conf and in /etc/rc.conf I have kldload /boot/modules/radeonkms.ko and again black screen. I have installed drm-legacy-kmod and xf86-video-ati-legacy but I tried also with new ati driver and drm for 12 and the same result. On the old system when I use ati driver version 7.9 and kldload radeon.ko from kernel worked without problem. On the old system the new ATI driver didn't work and none of the drm-kmod didn't work too. Now I am using scfb driver and it works. I do not know if is a bug in the drivers or something else. Thank you. Please check attached logs.

I did try to run FreeBSD 11.2 on the borrowed dock station and it boot (slow but...) and everything was O.K. - no black screen when switched to fb. I did also "startx" and open Openbox. The difference from the new system is that on the old drive I had freebsd-boot and uefi partitions but on the new one I have just uefi.

The black screen, this only happens when Xorg is running?

(In reply to Chris Rees from comment #3) I think this happened to me after upgrading a 12-STABLE system from r354521 to r357245. However, my system is unresponsive at this point. Rebuilding the modules did not help until I upgraded the poudriere jail from 12.1-STABLE (maybe r354521?) to r357245. Some KBI changed between the two revisions? It happened without Xorg at the moment radeonkms.ko was loaded. Hardware: vgapci0@pci0:1:0:0: class=0x030000 card=0x02721028 chip=0x94881002 rev=0x00 hdr=0x00 vendor = 'Advanced Micro Devices, Inc.
