But I have personally exeperienced this FC1 problem many times (especially on test SMP machines with the kernels older than 2.4.22-1.2174.nptlsmp). 2174 isn't as bad, as now 9 out of 10 times it correctly shuts down and goes past the unmounting faze. But the occasional lockup for no reason (with nothing logged to indicate any problems) still occurs occasionally, again though, more often on the older kernels than on the new 2174 one. Michael.
