Yes, the problem still exists. I could reproduce it with drm-tip commit 6dc8457a2f2093eecb9c6cbb7306fd25bb1664e6. I tested two times and the results were similar: all characters are broken and the system was unable to show GDM login screen. The system was accessible from SSH but it couldn't reboot. I ended up pressing 'R' on the Xen hypervisor console to reboot it.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
