Christopher Penalver, I finally got a chance to install 13.10 Saucy and retry this problem. The new unbind problem happens exactly described above. Reminder I am following these instructions: http://www.linux-kvm.org/page /How_to_assign_devices_with_VT-d_in_KVM
I happened to be root while running the unbind command and the result of the command kicks me out of root back to my normal user. Had I been a normal user I am not sure I would have found this bug as a normal user because the sudo command returns you to normal user after complete. root@apocalypse:/home/bruzer# echo 0000:01:00.0 > /sys/bus/pci/devices/0000\:01\:00.0/driver/unbind bruzer@apocalypse:~$ The kernel does not crash as before, but I don't think the unbind command is working properly in this situation. I think it is clear the kernal oops problem is gone but the unbind step in the list does not work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1190120 Title: Kernel Oops - unable to handle kernel NULL pointer dereference; after unbind of a PCI device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1190120/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
