OK, the freeze usually occurs a few seconds after lightdm starts up. I have worked around this by uninstalling lightdm and instead using startx to go straight into lxde. Since I no longer get the oops, my current dmesg probably isn't that useful.
I have attached kern.log.2 and syslog.2 which contain the relevant messages, and the other files mentioned in that document. ** Attachment added: "oops_log.tar.gz" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/961945/+attachment/2917064/+files/oops_log.tar.gz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/961945 Title: BUG: soft lockup - CPU#0 stuck for 92s!
