MORE DATA! I'm also having the "won't power down" problem -- "FAIL" message in red on the console. Xubuntu 64 bit, Oneiric 11.10
I use an edimax USB wireless dongle. However, when I switched to a TP-LINK TL-WN321G (stolen from my other near-identical machine, which doesn't have the problem) the problem went away. I don't have any network drives. Just starting up ubuntu with the edimax plugged in (and connecting automatically to my WPA network) is enough to cause the shutdown problem.
