Sudden and unexplained reboots

[Stefan Farrenkopf]

Hi Noor,

maybe you installed anything new which loads additional kernel modules or 
did you make any other modifications to your kernel which influence 
networking?

I had the same problem two days ago after I installed the vmware2 port on 
my FreeBSD desktop machine.
The problem was obviously that some related kernel module is not compatible 
with the IPXrouted (and vice versa).
Because I need the IPX routing daemon and I do not know how to track the 
problem down I removed vmware2 and the kernel module.

cheers,
STefan
