https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D264206 Emmanuel Vadot <manu@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Resolution|--- |Overcome By Events CC| |manu@freebsd.org Status|Open |Closed --- Comment #3 from Emmanuel Vadot <manu@freebsd.org> --- Your first problem is that you don't have the needed firmware, pkg install gpu-firmware-radeon-kmod-caicos should fix the attach problem. The second one is that somewhere in drm they leave some variable uninit and= we panic when we try to access them. This is fixed in 5.10 and tbh bisecting w= hich changed is needed to fix this in 5.4 is too complicated. --=20 You are receiving this mail because: You are on the CC list for the bug.
