Unfortunately I haven't had a chance to do the network test yet whilst in the hung state since my desktop switch is currently broken. If after reviewing the logs you still want me to try this, let me know and I'll try to work something out. The nouveau module was given the parameter debug=PGRAPH=debug and I did two attempts: the first file 3.11-rc3-dmesg.plugged is a boot with the DP connector plugged in (bad, hangs) whilst the second file 3.11-rc3-dmesg.unplug is a boot without the DP connector plugged in (good, but standalone mode only). I see there are some mentions of switcheroo in the logs which is interesting given that I'm currently running it in Discrete Graphics (nVidia mode) without Optimus enabled in the BIOS. Many thanks, Mark.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
