Hello,
We have a number of systems running KM400 chipsets from VIA (Socket A/462). Two different models have produced the same results -- DFI KM400-MLV and MSI KM4M-V. When a /sbin/reboot or /sbin/shutdown -r now is issued, the system does everything you would expect from a reboot, but when it gets to Rebooting System, it hangs and requires a power cycle.
The logs do not indicate anything is going wrong. It's not a kernel panic. I've tried appending "acpi=off noapic" or just "apci=off" to grub.conf and neither help. We've tested these boards extensively with various CPU's, hard drives, and RAM and they show no other issues, so it's not hardware defects or hardware compatibility issues.
I'm not sure what is going on, but assistance would be greatly appreciated.
Thanks.
Forgot to mention -- this is on CentOS 4.4 i386.
Thanks.

Dunno, but I'd be messing around with the BIOS. Usually there's something there that you have to tweak. Turn stuff on/off that looks right. Look for stuff about turning on/off power management, apci, etc.
(Obvious: don't mess with CPU speed, clock speed, HDD settings, etc)

These systems have been running fine with no problems with a Redhat Linux derivative (CentOS or Fedora) or FreeBSD for over two years already, so I don't think it's really necessary to do anything there.
We recently did fresh installs of CentOS 4.4. That's when the problem started happening. The system works perfectly fine otherwise, it's just a problem with the reboot process. Since these are servers in a data center, it's vital that they be able to reboot without intervention.
Did something significant change with CentOS 4.4 that could be causing the problem?
Thanks.

I am having exactly the same problem. It is probably a similar motherboard (DFI, but cannot check right now). I recently converted this box from FC4 to CentOS4.4. If I am not mistaken, it did not have the shutdown issue when FC4 was running.

We appear to have solved the issue by pulling down the latest version of the kernel from the CentOS testing/development site.
wget http://dev.centos.org/centos/4/testing/i386/RPMS/kernel-2.6.9-42.37.EL.c4tes... rpm -ivh --nodeps kernel-2.6.9-42.37.EL.c4test.i686.rpm reboot
I was able to reboot the test system six times with no problem so far. I will report back if anything changes.
Thanks.

Unfortunately, that kernel did not help in my case. Rebooting stops after displaying "Starting System" and I have to use the power switch.

Turns out the problem was not related to CentOS. The system is connected to a KVM switch. When I stopped using the switch, rebooting went through normally. This is the first time I see this kind of problem with the KVM switch, but it is probably some irregularities with the motherboard (DFI K8M800-MLVF).
