Not much cursor activity, so that was indeed a red herring. Your machine also uses a phys_attach for the overlay registers, but that should not have been affected as it isn't exposed to userspace and so doesn't take part in mmap or pwrite. Weird. Honestly, there's a slim chance it's unhappy with the overlay register mapping.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
