For debugging, if there is no IPMI or IP-KVM and syslog to remote server 
does not help, you may try to get a "netconsole".
This is kinda rustic, the sender is set up via a kernel boot argument, 
the receiver is a raw network socket (netcat works). No authentication, 
no encryption, no routing (sic! must be within same IP subnet).
Check this links:
