I recent upgrade my system from 9.10 to 10.04. I'm using the old kernel to report this lines. When I'm upgrading trough Update Manager (it took about 4 hours but yet i don't know) i leave alone in the process, when i return i found a black screen and i think that is the screen saver, when i move the pad and press some key and doesn't have response i press alt + ctrl + f1 to get the tty without responce then press ctrl + alt + del and again no response then i made a hard off, pressing the power bottom and restart it, when the grub load i found 4 kernels that is ...-14, ...-20, ...-21 and ...-21 i select the first one ...-21 but only gets black screen, then trying one by one trough, and get that -20 boot but without mousepad and the old and new boot splash.

A addition I have the same problem at -20 kernel but is not permanently a only a incompatibility with the b43-fwcutter package and i found a workaround changing the brightness of the screen (don't ask how i only know that it works), with the new kernel say something about mounting sda4 or like that i will take note later.
