I have seen similar behaviour on my Athlon Dual core 4GB RAM, Nvidia chipset, edubuntu 8.04 server connected to 1 ltsp client. For me it was period of inactivity. Seems like if I let the system on for couple of hours, it just freezes with the same behaviour.
I then found that it would freeze even without the client booted. Hence I am sure that for me it is not LTSP. I suspect that it is some power down configuration in the chipset that is messing things up. However I donot see any log messages to debug.
