For some reason, related to my current distro, i didn't used init=/bin/sh .
The full, bloated, log is here http://www.webalice.it/ceztko/log1
(taken from launch of "poweroff"). I can confirm, as Rolf Offermanns
noted, that "halt -f" doesn't cut the power.

An extract is here. However i'm worried that the log is trunkated. Is
netconsole good enough to use in this case?
