https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=234646 Bug ID: 234646 Summary: kldload radeon kms - black screen Product: Base System Version: 12.0-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: lumiwa@gmail.com Created attachment 200816 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=200816&action=edit 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. -- You are receiving this mail because: You are the assignee for the bug.
