Broken In
hey guys,
i was updating ubuntu 11.04 to 11.10 using the built in update manager. i downloaded all the packages and then the top right corner button(used fr shut down,restart etc) turned red i clicked it an instead of restart option it as written "restart to complete update".i clicked it then after it restarted i clicked the ubuntu 3.0 something that was the first option which was always used to enter ubuntu.i also add that my tata photon + modem was connected to my laptop.
But after the normal orange & white lights happened and then this is shown on the screen:
* Starting anac(h)ronistic cron [OK]
* Stopping save kernel messages [OK]
* Starting regular background program processing daemon [OK]
* Starting deferred execution scheduler [OK]
* Stopping anac(h)ronistic cron

WHEN I TAKE OUT TATA PHOTON +:-
[ 571.716611] option: option_install_callback: error -108

WHEN I TURN OFF BLUETOOTH THEN:-
