cpuspeed was off. If I say 'shutdown -h now', the machines powers off
after a clean shutdown. If I say 'shutdown -r now', it brings the
machine down. The last steps are remounting md0 readonly and syncing
the SATA drives. The last line it prints on the screen is 'Restarting
system'. Then, it just sits there. I have to use the front-panel
switch to turn it off, then power it back on. Which is a bummer if
you have to reboot it remotely. Btw, the front-panel switch is one of
these new types when you have to hold it down for several seconds
before it actually powers the machine off.
I'm wondering if it's some hardware problem. It's my understanding
that a restart is basically like a push button reset. The last thing
the CPU does is pull the reset line (A20 or A21 ??) which causes the
M/B to go through its boot-up. But, now with ACPI and these smart
power supplies, I was wondering if somehow this is the cause of my
problem.
Any other suggestions?
I suspect this is an ACPI or chipset support problem which has been
fixed in a later kernel. I have a couple of computers with the same ASUS
M2NPV-VM motherboard (BIOS version 0801) and halting and rebooting works
fine under CentOS 5.0 but hangs under CentOS 4.3. However, under CentOS
4.3, if I add acpi=off to the kernel boot command line, reboot works but
not halt.

Do you mean that a cold boot (from power off) works, but a warm
reboot doesn't? Try turning off cpuspeed:
# service cpuspeed off
and then try again (starting with a cold boot). We saw this with an
Opteron board.
