In single user mode installworld gets stuck

In single user mode installworld gets stuck at random place.  This
happens on real boxes w/ ahci and w/ nata.  This also happens in
virtual machines.
Pressing ctl-z and then running 'fg', could get installworld out of
stuck state, however, it still could get stuck later on.

In contrast, in normal mode, installworld will not get stuck as far as
I have tested.

Best Regards,
