I experience the same errors indicated above only my hang is momentary with system shutdown being successful. I have a fresh install of 8.04 (not upgraded from 7.10) on an old Dell Dimension XPS T450 home PC with a processor upgrade to Intel 1.3 gigs. I'll wait for a cure to be posted to find a resolution. For now it's not a big problem just a nuisance.
