[CentOS] System hangs at "Rebooting System" on VIA KM400 chipsets
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. nethub at gmail.com wrote:> Hello, > > We have a number of systems running KM400 chipsets from VIA (Socket > A/462).

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) -Ben On Tuesday 23 January 2007 17:02, nethub at gmail.com wrote:> Hello, > > We have a number of systems running KM400 chipsets from VIA (Socket > A/462).

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. Akemi
