If you're looking at the "STATE" column, I believe this is normal (looking
at top on my dual P3 system); from what I understand, the "C" column next
to it shows what CPU the process is running on (I have a mix of zeros and
ones in that column). The "CPU0" and "CPU1" entries in the "STATE" column
seem to have something to do with when a process switches from one CPU to
another.
Of course, it seems that the top(1) manpage hasn't been updated in ages,
so I'm not sure about any of this :)
