This is the only kernel that has worked for us consistently. It is on 70 or so other servers and runs without any problems. I dont see this message on any of our P3 systems - only the systems that have the P4s. It's refreshing to know that this is not the cause of the crashes - however the issue still remains that this one system is freezing and there is no information in any of the log files, nor is there any output to the screen when the system does freeze. The times of the crashes arent the same - fsck completes with no problems, and the only message I see in /var/log/messages is "restart" - never any errors. Im stuck on what to do next... Thanks again for your help - and can you please CC me on any reply - i dont subscribe to linux-smp.
