FWIW I saw this the other day on a real-machine CentOS 5.2
system after a severe crash in which the system put all the
drives into read-only mode.  The machine had to be
power-cycled and dovecot complained the clock was off by 5
minutes.  Maybe something else going on with the 2.6.18
kernel?  Dunno.
