I hade made a clean install to 8.04, the problem persist . I had it on 7.10 and 7.04 .
Before I try a Kubuntu and it did shutdow power correctly.
Only for testitng porpuose I made a "halt" command on the shell of "recovery mode" and works ok.
I dont undestand what the ubuntu is doing when trying to shutdown but looks that something hang up things.
