My machine configuration is pentium 4 with 256 mb memory, excell motherboard, vga on board with savage chip. When I installed karmic, I received that error.

But when I restarted the ubuntu it gave me the same result. I searched through all google but no luck. Finally I re-installed the ubuntu and the error is gone.
Funny isn’t it. I think this is a bug for some hardware.
