I nstall ubuntu 12.04 recently on a DELL inspiron 1440 notebook. I think the chipset is GM45 something. I am quite fresh on linux operation system. I do not know how could I solve this problem. It seems not only me have this problem.

I install ubuntu 12.04 64bit and windows 7 64bit on my notebook. Every time I enter the ubuntu, I will notify me this problem for 4-5 times. It say "sorry, Ubuntu 12.04 has experienced an internal error". the detail are as follows:
