Had this problem earlier: Crash after update to 11.10, from 11.04; ran the solution and had everything updated and upgraded.
I get the following lines after booting with some of the preceding
[OK] lines as the other topic.
* Checking battery state... [ 21.640534] btusb_intr_complete: hci0 urb ffff88011e948480 failed to resubmit (19) [ 21.640690] btusb_bulk_complete: hci0 urb ffff88011e948cc0 failed to resubmit (19) [ 21.640734] btusb_bulk_complete: hci0 urb ffff88011e9480c0 failed to resubmit (19)
tty2 and execute
startx to start the GUI that I'm using right now but Ubuntu won't boot without it.
