[I'm including both graphics and x11 becasue I haven't been able to narrow it down, and because extra brains might see something.] Hello: 1) I have an older and64 system with a Radeon HD 3300/RS780 gpu. 2) I recently upgraded it from 11-RC2 to FreeBSD 13.0-CURRENT r344507 amd64 and recompiled (from source) _all_ installed ports. 3) When I originally booted the new system, it was not using any of the new drm system ... and everything worked fine using the vesa driver. (Slowly, but fine.) With the oft-tested patience of Niclas Zeising (zeising+freebsd@daemonic.se) I got drm-legacy-kmod and gpu-firmware-kmod working. Sort of. 4) With: kld_list="/boot/modules/radeonkms.ko" in rc.conf, the system boots, recognizes the gpu, comes successfully to the console with vtys 1-11 enabled. Every that needs text mode runs correctly and the system is stable. 5) If I start xdm, the login screen appears and accepts input. If I don't actually log in, this is also stable (for 24 hours and counting). 6) If I _do_ log in, .xsession is processed correctly and the display accepts input. However: the system will then panic after a time ranging from 60 seconds to 30 minutes. This happens even if the only two programs running are the window manager (fvwm) and xmessage (used to end the X session) and there's no activity on mouse or keyboard. And: while the system is up, moving/resizing a window will - sometimes - leave visual artifacts on the screen. 7) Superficial examination of the crash dumps appears to show a variety of memory errors; analysis beyond that is why I'm here. 8) The last three crash dumps, along with dmesg.boot, xorg.conf and Xorg.0.log, can be found at: http://209.6.230.48:8888/~huff/crash/ 9) If this is something I caused - /mea maxima culpa/. I just want to find out what's happening and fix it (if possible). Respectfully. Robert Huff
