Hello, I've got an EPIA-M series motherboard in a system that has locked up twice under random conditions. Nothing is logged to the console or logs, the system just hangs.
The system is installed with CentOS 4.4 and running the 2.6.9-42.0.8.EL i686 kernel. I am aware that older C3 processors had the CMOV problem, but that is resolved in the later boards (procinfo below). I've seen a few posts about similar problems, but it's not clear whether this is a bad board, or if there's an issue with the kernel.
cpuspeed was running, I've since disabled and stopped the service as it's been rumored to cause problems. This was mentioned in this bug report that is still open :
http://bugs.centos.org/view.php?id=1270
Can anyone confirm that there are no known problems with the VIA C3 Nehemiah Model 9 and CentOS, or if some (kernel) tweaks are required to make these systems stable?
Regards, Chris
