I recently upgraded to Ubuntu-9.10 from 9.04 ( which are really good), but now my system hangs very frequently and the only way I can get to work is to shutdown and restart the computer. On an average it is 10-15 time a day. Upon hanging, I cann't type anything except the mouse right click works. I have to showdown the machine not using the system command but manually poweroff the machine. I am not quite sure how to pose the question properly which might help someone to pin-point the solution, also I am not sure whether my decision to upgrade was correct one. The feeling is similar to upgrading from windows XP to Vista and then repenting.
