Roger,

hmm, it's a gateway which is the connection to the world for a bunch 
of users, also the endpoint of 4 IPSec tunnels, the main DNS server 
for a whole company, pptp server for road clients... well, I don't 
think I can take it offline for too long. ;)

There's nothing of interest in the logs (I suspect it's too late to 
have any daemon write something to syslogd as the system is then 
dead). As I also think, this is somehow related to network traffic, 
I'll try to monitor it's traffic starting tomorrow. The tech guys at 
the office there have to install a hub first (yes, it's remote to me 
which makes investigation harder).

As I think (well, guesswork) this might be related to GRE traffic 
(the poptop server), I may stop this traffic at the firewall (and 
take the service to another machine).

What's the version of the system you're having trouble with? Is it 
pre-6.2?

I'm wondering if your machine also passes GRE traffic? Does it 
provide pptp services?

I've attached the latest dmesg, can you see any similarities (as it 
still might be a hardware issue)?
