The close the sessions on display :1, when I switch to the session on display :0 the system reboots. I have an amd64 with a ATI radeon card: drm0: on vgapci0 Note that if I never close either X11 session there is no problem with stability (weeks uptime), however the only graphics intensive app I use is mplayer. mplayer is the only reason I need drm, however the bug will be triggered even if I havn't used mplayer in my X11 session. I will attach the output from dmesg with my full system setup and the output from the two xorg log files. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
